Examples
The following examples show how to use hints:
| • | To force an index scan when polling in an Oracle database, set the property as follows: |
adb.p1.poll.hint /*+INDEX(P1,P1_INDX)*/
where p1 is the publisher table, and P1_INDX is the index created on the publishing table.
The adapter will execute this select query on the publishing table:
SELECT /*+INDEX(P1,P1_INDX)*/ * FROM P1 WHERE ID = ?
| • | To use NOLOCK hint when polling in as SQL Server database, set the property as follows: |
adb.p1.poll.hint WITH(NOLOCK)
where P1 is the publisher table.
The adapter will execute this select query on the publishing table, but will not issue shared locks or honor exclusive locks:
SELECT * FROM P1 WITH(NOLOCK) WHERE ADB_L_DELIVERY_STATUS =’N’
| • | To force an index scan when the adapter fetches records from a child table set the property as follows: |
adb.C1.poll.hint /*+INDEX(C1,C1_INDEX)*/
where C1 is the child table, and C1_INDEX is the index created on the child table.
The adapter will execute this select query on the child table:
SELECT /*+INDEX(C1,C1_INDEX)*/ * FROM C1 WHERE ID = ?
