Variable Inside the Access Pass Through Query

Question

I set a global variable in my program.

public this_is_global_var as integer

this_is_global_var=1

Then I use that variable inside my pass through query

Select * from oracle_table where id=this_is_global_var ;

But error shows "this_is_global_var: invalid identifier"

Please help.Thanks.

Answer 1

如果要在查询中使用变量，则必须将其编写为变量：

"SELECT * FROM oracle_table WHERE id = " & this_is_global_var

Answer 2

You can define placeholders for variable inside the query definition and replace it before execution.

qdfTemp.SQL = Replace(qdfMyQuery.SQL, "[this_is_global_var]", str(this_is_global_var))

and then execute temp query. Original query will be untouched.
