Insert, Update, Delete, and Select operations on Oracle tables and views
The Microsoft BizTalk Adapter for Oracle Database surfaces a set of standard operations on each Oracle database table and view. By using these operations, you can perform simple SQL INSERT, UPDATE, SELECT, and DELETE statements qualified by a WHERE clause on the target table (or view). These operations are also called data manipulation language (DML) operations. To perform more complex operations, for example a SQL SELECT query that uses the JOIN operator, you can use the SQLEXECUTE operation. For more information about the SQLEXECUTE operation, see SQLEXECUTE Operation in Oracle Database.
The following table shows the DML operations that the Oracle Database adapter supports:
| Operation | Description |
|---|---|
| Insert | Performs an Insert operation on the target table or view. The Insert operation supports multiple record or bulk inserts into the target table or view: - A multiple record Insert operation inserts rows into a table or view based on a supplied record set. - A bulk Insert operation inserts rows into a table or view based on a supplied SQL SELECT query and column list. The records that the query returns are inserted into the target table based on the column list. The return value for an Insert operation is the number of rows inserted. Note: Both multiple-record insert and bulk insert cannot be combined in the same message. InlineValue For all simple data records in a multiple record Insert operation, you can choose to override the value of a record by specifying a value for an optional attribute called InlineValue. The InlineValue attribute can be used to insert computed values into tables or views such as populating the primary key column using a sequence or inserting system date (using SYSDATE) into a date column. For example, in the following INSERT statement: <Insert xmlns="http://Microsoft.LobServices.OracleDB/2007/03/SCOTT/Table/ACCOUNTACTIVITY"> <RECORDSET> <ACCOUNTACTIVITYRECORDINSERT> <ACCOUNT>10001</ACCOUNT> <EMPNAME>John</EMPNAME> <AMOUNT>1500</AMOUNT> <TRANSDATE InlineValue="SYSDATE">2008-06-21T15:52:19</TRANSDATE> </ACCOUNTACTIVITYRECORDINSERT > </RECORDSET> </Insert>Even though “2008-06-21T15:52:19” is specified as a value for the TRANSDATE column, the value of the InlineValue attribute, “SYSDATE,” (system date) will be inserted into the target table. While using the InlineValue attribute: - Avoid using constant values for the InlineValue attribute. For example, in the INSERT statement, if you specify <EMPNAME InlineValue="John"/> then it will result in an error. This is because the value of the InlineValue attribute is passed on as-is to Oracle, and in this case John is passed to the Oracle database, which is not the expected value (expected value is ‘John’). You would have to use single quotes around the employee name. For example: <EMPNAME InlineValue="’John’"/>.- If you want to use a select query for the InlineValue attribute, you must enclose the SELECT statement in parentheses and also ensure that the select query fetches only a single record. For example: <EMPNAME InlineValue="(SELECT NAME FROM MS_SAMPLE_EMPLOYEES WHERE ID=123)"/>.Note: If an element is marked as NOT NULL in the Oracle database, you must specify a value for that element even if you have specified an inline value. Failing to do this will cause the schema validation to fail. |
| Select | Performs a SQL SELECT query on the target table or view based on a supplied list of column names and a filter string that specifies a SQL WHERE clause. The return value for a Select operation is a strongly-typed result set that contains the specified columns and rows. |
| Update | Performs an Update operation on the target table or view. The records to be updated are specified by a filter string that specifies a SQL WHERE clause. The values for the update are specified in a template record. The return value for an Update operation is the number of rows updated. |
| Delete | Performs a Delete operation on the target table or view based on a SQL WHERE clause that is specified in a filter string. The return value for a Delete operation is the number of rows deleted. |
