I have a series of querys in my application that retieve data base on certain conditions.

I have a selection of records displayed in a grid that have been retrieved by a SQL query.

I want to copy/insert these records and all fields and values into a new table.
I need to copy the data into a table but only if a certain condition is met.

Example:

Copy all records that have been retrieved in the grid into my new table but only if they meet a True condition in a field called Flag.

Is it possible to do this in SQL or any other way.
Many Thanks

yes, depending on your database this statement sceleton should do it

for a existing empty table
insert into tablename (maybefieldlist_is_optional) select fieldlist from othertablename

for a new table
create table tablename as select fieldlist from othertable

use the execsql-method to fire the sql-statement


there is also a component-method (batchmove)
you need a ttable
fill in the databasename at runtime
fill in the tablename at runtime
use a code like

table1.batchmove(query1.batCopy);

hope this helps

oops typo
table1.batchmove(query1.batCopy);
should be
table1.batchmove(query1,batCopy);

If I used your code below:

'for a existing empty table
insert into tablename (maybefieldlist_is_optional) select fieldlist from othertablename'

can I use a Where clause as I only need to copy the records that match a criteria?

Thanks

sure you can :)

insert into tablename (maybefieldlist_is_optional) select fieldlist from othertablename where condition(s)

only a order by is mostly not allowed

depending on the SQL server you use you could also construct a query like this (MSSQL):

insert into tblTwo
(fldOne, fldTwo)
select
  fldOne, fldTwo
from
  tblOne
where
  etc etc

this is also possible for update queries

Thanks Meikl but I have used this SQL query and I receive an Invalid Parameter error when running.

Insert Into SagePost(ContractNumber,
CustomerName, AccountRef, FeeType, MonthlyFee,
JoiningFee, ContractStartDate, ContractEndDate)

Select Contract.'Contract Number', Customer.'Customer Name', Customer.'Acc Ref', Contract.'Fee Type', Contract.'Monthly Fee'Contract.'Joining Fee', Contract.'Contract Start Date',Contract.'Contract End Date'
From Contract, Customer
Where Customer.'Contract Number' = Contract.'Contract Number' and
Contract.'FirstInvoice' = False and Contract.'COption' is null

Any Ideas?

Thanks

Select
  Contract.'Contract Number',

  Contract.'Joining Fee',
  Contract.'Contract Start Date',
  Contract.'Contract End Date'
From
  Contract,
  Customer
Where Customer.'Contract Number' = Contract.'Contract Number'
  and Contract.'FirstInvoice' = False
  and Contract.'COption' is null

was this a typo posting here or is the comma really missed?

The comma was actually missing. Thanks for that.
But even with the comma in place I still receive the error message 'Invalid Parameter'.
This message even occurs with this query:

INSERT INTO SagePost
SELECT CONTRACT.'CONTRACT NUMBER'
FROM CONTRACT;

Any ideas? or is there a help file anywhere with error code explanations?

Thanks again

hmm,
just guessing,

you have a blank in your fieldname,
does this change help?

INSERT INTO SagePost
SELECT "CONTRACT.CONTRACT NUMBER"  //or CONTRACT."CONTRACT NUMBER"
FROM CONTRACT;

singlequotes are on some databases
interpreted as string-value rather than as fieldname

but, just guessing
