Answer 1

Hi,
s the attribute action with the value INSERT, UPDATE, UPDATE_INSERT, DELETE, or SELECT. If you use the optional <table> element, the value specified is used as a database table name.
1.Action=UPDATE
  Statements with this action cause existing table values to be updated. Therefore, the statement corresponds to an SQL UPDATE statement.
The corresponding SQL statement for StatementName1 in the example above is as follows:
UPDATE dbTableName  SET col1=u2019val1u2019, col2=u2019val2newu2019 WHERE ((col2=u2019val2oldu2019 AND col4=u2019val4u2019) OR (col2=u2019val2old2u2019))
2. Action=UPDATE_INSERT
The statement has the same format as for the UPDATE action. Initially, the same action is executed as for UPDATE. If no update to the database table can be made for this action (the condition does not apply to any table entry), values of the table described in the <access> element are inserted in accordance with the description of the action INSERT. <key> elements are ignored in this case.
3.Action=DELETE
Statements with this action cause existing table values to be deleted. One or more <key> elements formulate the condition for which table values are deleted.
The corresponding SQL statement for StatementName3 in the example above is as follows:
DELETE FROM dbTableName  WHERE ((col2=u2019val2oldu2019 AND col4=u2019val4u2019) OR (col2=u2019val2old2u2019))
4.action=SELECT
Statements with this action cause existing table values to be selected. Therefore, the statement corresponds to an SQL SELECT statement.
5.Action=EXECUTE
Statements with this action result in a stored procedure being executed. The name of the element is interpreted as the name of the stored procedure in the database.
