• Microsoft Excel has built-in feature of connecting excel to oracle database and we show show you how to use it.
• Once the connection is established, you will be able to access all the files in the oracle database of that common particular user.
• In our case, c##sqlserverguides is the name of our common user name. Please note that it is mandatory to c## as suffix while creating a user name.
• There are three things required to connect excel with the oracle database.
  • Server or SSID
  • Username
  • Password
• Default ssid is “orcl” which is also the Global Database name. In case you have changed it or created a new one then please mention that one.
• Open Microsoft Excel and click on the Data tab, from there click on the the From Database dropdown and select ‘From Oracle Database‘.

• If you encounter this error then simply click on the on the OK button. The error won’t create problem while connecting excel with the Oracle database.

• Enter the name of server or ssid here. ssid is the name of the global database created at the time of installation. In our case, it is ‘orcl’, click on the ok button to proceed.

• Excel is connected to oracle database now you can browse of all the oracle data on the microsoft excel.

Connect Excel to Oracle Database with ODBC

In this section, we will learn how to connect excel to the oracle database on the windows operating system.

• Offline installed Excel software can only be connected to the oracle database. Web based excel won’t give option to connect with the database.
• First step in the process is we have to create a new data source on “Windows Administrative Tools” on windows operating system.

• Inside “Windows Administrative Tool” click on the ODBC Data Sources (64-bit). From the appeared prompt select “User DSN” tab and click on Add button.
• Another prompt will appear “Create New Data Source” in that prompt select “Oracle in OraDB19Home1“. This name may change in future but it will always start with the key ‘oracle’. Click on the the finish button.

• Once you clicked on the finish button in the previous option, you will see “Oracle Database Driver Configuration” window.
• Data Source Name: Name provided here will reflect in excel and you have to choose it over there.
• Description: If you want to add a little description about your database you can write it here. Description can also be treated as instruction for other users of the database.
• TNS Service Name: ‘orcl’ is the global database configured while installing the Oracle databse software. Incase you have changed it or created a new one then mention that here.
• User ID: It is optional to provide user id. You can mention the common username here.
• Click on the “Test Connection” button and provide the username and password and click on the ok button. If a prompt appear “Test Successful” that means you can move to next step now. Click on the Ok button on the “Oracle ODBC Driver Configuration” window.

• Open Microsoft Excel and click on the Data tab, from there click on the the Get Data dropdown and select ‘From Other Sources‘, click on the option “From ODBC“.

• Select the Data Source Name that we created in Oracle Odbc Driver Configuration.
• Once done, it will ask for the username and password. Enter the credential and you will see that a screen with Navigation title will appear and now you can browse your data there. This is how we can connct excel with oracle database.

Excel Connect to Oracle Database without ODBC

In this section, we will learn how to connect excel connect to the oracle database without ODBC on the windows operating system.

• Most of the connection between microsoft excel and oracle database are established using ODBC.
• This type of connections are established in previous versions of microsoft excel when there was no option for from connecting oracle directly with excel.
• In new versions there is already option to connect with oracle database as you can see in the below image.

• In case this option is not available then using oled you can connect with the database.
• to see practical implementation of excel connect to oracle database with oled visit the first section of this tutorial ” Connect Excel to Oracle Database”.

Excel Connect to Oracle Database using OLED

In this section, we will learn how excel connects to an oracle database using OLED in the Microsoft Windows operating system.

• Open Microsoft Excel and click on the Data tab, from there click on the the Get Data dropdown, now click on ‘From Other Sources‘ and select From OLEDB.

• In the connection string prompt enter the below code. In our case ‘orcl’ is the name of our global database so we have set source=orcl.

provider=OraOLEDB.Oracle.1;data source=orcl

• After entering the above code click on the build button a new promot will appear “Data Link Properties”. Enter the user name and password for the user you want to connect with. In our case we are connecting with “c##sqlserverguides”.
• Once filled all the required information (username & password) click on “Test connection” button. If Test connection succeeded click on ok for all the three screens.

• New prompt will appear immedietly after clicking on ok button of “From OLE
  DB” window.
• Enter username and password one last time and click on connect. It may take few seconds then excel will be connected to oracle database.

• Below is the window that will appear on the successful establishment of the connection. You will be able to access all the files, folder and tables available inside the connected user.

Excel Connection String to Oracle Database

In this section, we will learn how to establish an excel connection string to an oracle database.

• While connecting excel to oracle database you must have noticed ‘Credential Connection String’ box that might be optional in some cases.
• Excel Connection String holds all the information about the connecting database like host, hostname, port, IP address, server type and service name.
• while connecting excel to oracle database using oled we have to provide excel connection string that you can us the below excel connection string to connect with oracle databse.

provider=OraOLEDB.Oracle.1;data source=orcl

• If you are advance user and want to connect via oracle database on server than you can configure the setting using the below code.

provider=OraOLEDB.Oracle.1;data source=
             ("
              DESCRIPTION = 
                 (ADDRESS = 
                   (PROTOCOL = TCP)
                   (HOST = localhost)
                   (PORT = 1521)
                 ) 
              (CONNECT_DATA = 
                  (SERVER = DEDICATED) 
                  (SERVICE_NAME = orcl))
              )"

I’ve been thinking about it for quite a long time and never really had time to implement it, but it’s finally there : a pipelined table interface to read an Excel file (.xlsx) as if it were an external table.

It’s entirely implemented in PL/SQL using an object type (for the ODCI routines) and a package supporting the core functionalities.
Available for download on GitHub :

/mbleron/ExcelTable

Usage

ExcelTable.getRows table function :

This is the actual SQL interface, to be used in conjunction with the TABLE operator.
It returns an ANYDATASET instance whose structure is defined by the p_cols parameter.

  function getRows (
    p_file   in  blob
  , p_sheet  in  varchar2
  , p_cols   in  varchar2
  , p_range  in  varchar2 default null
  ) 
  return anydataset pipelined
  using ExcelTableImpl;

Range syntax specification

 range_expr ::= ( cell_ref [ ":" cell_ref ] | col_ref ":" col_ref | row_ref ":" row_ref )
 cell_ref   ::= col_ref row_ref
 col_ref    ::= { "A".."Z" }
 row_ref    ::= integer

If the range is empty, the table implicitly starts at cell A1.

Otherwise, there are four ways to specify the table range :

• Range of rows : '1:100'
  In this case the range of columns implicitly starts at A.
• Range of columns : 'B:E'
  In this case the range of rows implicitly starts at 1.
• Range of cells (top-left to bottom-right) : 'B2:F150'
• Single cell anchor (top-left cell) : 'C3'

Columns syntax specification

The syntax is similar to the column list in a CREATE TABLE statement, with a couple of specifics :

 column_list    ::= column_expr { "," column_expr }
 column_expr    ::= ( identifier datatype [ "column" string_literal ] | identifier for_ordinality )
 datatype       ::= ( number_expr | varchar2_expr | date_expr | clob_expr )
 number_expr    ::= "number" [ "(" ( integer | "*" ) [ "," [ "-" ] integer ] ")" ]
 varchar2_expr  ::= "varchar2" "(" integer [ "char" | "byte" ] ")"
 date_expr      ::= "date" [ "format" string_literal ]
 clob_expr      ::= "clob"
 for_ordinality ::= "for" "ordinality"
 identifier     ::= """ { char } """
 string_literal ::= "'" { char } "'"

Column names must be declared using a quoted identifier.

Supported data types are :

• NUMBER – with optional precision and scale specs
• VARCHAR2 – including CHAR/BYTE semantics
  Values larger than the maximum length declared are silently truncated and no error is reported.
• DATE – with optional format mask
  The format mask is used if the value is stored as text in the spreadsheet, otherwise the date value is assumed to be stored as date in Excel’s internal serial format.
• CLOB

A special “FOR ORDINALITY” clause (like XMLTABLE or JSON_TABLE’s one) is also available to autogenerate a sequence number.

Each column definition (except for the one qualified with FOR ORDINALITY) may be complemented with an optional “COLUMN” clause to explicitly target a named column in the spreadsheet, instead of relying on the order of the declarations (relative to the range).
Positional and named column definitions cannot be mixed.

For instance :

  "RN"    for ordinality
, "COL1"  number
, "COL2"  varchar2(10)
, "COL3"  varchar2(4000)
, "COL4"  date           format 'YYYY-MM-DD'
, "COL5"  number(10,2)
, "COL6"  varchar2(5)

  "COL1"  number        column 'A'
, "COL2"  varchar2(10)  column 'C'
, "COL3"  clob          column 'D'

Examples

Using this sample file :

1- Loading all six columns, starting at cell A2, in order to skip the header :

SQL> select t.*
  2  from table(
  3         ExcelTable.getRows(

  6         , ' "SRNO"    number
  7           , "NAME"    varchar2(10)
  8           , "VAL"     number
  9           , "DT"      date
 10           , "SPARE1"  varchar2(6)
 11           , "SPARE2"  varchar2(6)'
 12         , 'A2'
 13         )
 14       ) t
 15  ;
