Hi In Interbase, does anybody know how to use an expression in the "group by" clause, e.g.: select extract (month from HIRED_DATE) HIREDMONTH, count(*) EMPLOYEECOUNT from employee group by extract (month from HIRED_DATE) or select extract (month from HIRED_DATE) HIREDMONTH, count(*) EMPLOYEECOUNT from employee group by 1

Hi, I have searched for 'simple' stuff in using FireDac but havn't found the answer to the following, which would save me lots of keying ... I have a datamodule with a fdQuery & Datasource, and the fdQuery has the following: 'Select * from tTable where Company = :pC order by oOrderName' - so a parameter is created in the query. If in my code I want to set the query to different values do I have to do the select statement again in it's entirety, like: dm.fdc.Open( 'Select * from tTable where Company = :pC order by oOrderName', [ 'Debenhams'] ); Or can I simply specify the new parameter value like: dm.fdc.Open( '', [ 'Woolworths' );

Hi I'm having great difficulty in getting the syntax correct on a query I need to make via a Firedac Q!uery. Basically I want to set a WHERE clause that picks up all records that have a 'S' or 'R' in a certain field. In 'normal' SQL this codes like this: SELECT * FROM tTableName WHERE Status IN ('S', 'R') ORDER BY EventDate ... which works fine on the SQL Server, but how do I do this via a Firedac query? It may look something like this: qQueryName.Open('SELECT * FROM tTableName WHERE Status IN :pSR ORDER BY EventDate',[ ('S','R') ] ); The issue is how do I format the parameter - the above doesn't work, nor any of the different ways I can think of of setting the parameter to 'S','R'. Any help would be appreciated.
