数据库要用到UDF(ib_udf.dll)中的SUBSTR函数,在IBConsole中的Interactive SQL中执行
DECLARE EXTERNAL FUNCTION SUBSTR
CSTRING(80), SMALLINT, SMALLINT
RETURNS CSTRING(80) FREE_IT
ENTRY_POINT 'IB_UDF_substr' MODULE_NAME 'ib_udf.dll';
注册函数通过,但是执行
select substr(field1,1,4),field2 from table1
时出错:
Invalid request BLR at offset 81
function SUBSTR is not defined
module name or entrypoint could not be found
如何解决,请各位大虾帮帮忙,我对interbase不是很通!!!!
分数还可再加!!!!!!!
