The substr function is in the ib_udf file and is not automatically declared
for Interbase. You must register the udf before using it and make sure it is
in the UDF directory under your Interbase installation.
with MyQuery do begin
SQl.Text := 'DECLARE EXTERNAL FUNCTION substr CSTRING (256),' +
'SMALLINT, SMALLINT RETURNS CSTRING (80) ' +
'ENTRY_POINT "IB_UDF_substr" MODULE_NAME
"IB_UDF"';
ExecQuery;
end;
