SQL statements:
The SQl statements are used to fetch/retrieve update insert delete data from the database. In PeopleSoft we use the sql stmts using sqlexec or createsql. Differnet sql statements are:
Select Insert Update Delete.
Meta Sqls:
Differnet RDBMS have differne date and time formats. though the component processor takes care of the automatic convesion but at the time of using the sqlexec the automatic conversion does not take place. So in order to understand this the meta sql concept has come. Whcih we can use in diff sql stmts. for example datetimein date time currentdatetime datetimeout etc.
dateIn: This is used in the where caluse of Select and update
dateout: This is used while selecting the data.
