Dynamic SQL Comma-Delimited Value Query

由 我是研究僧i 提交于 2019-12-01 06:04:44
问题 [Update: Using SQL Server 2005] Hi, what I want to do is query my stored procedure with a comma-delimited list of values (ids) to retrieve rows of data. The problem I am receiving is a conversion error: Conversion failed when converting the varchar value ' + @PassedInIDs + ' to data type int. The statement in my where-clause and error is: ... AND (database.ID IN (' + @PassedInIDs + ')) Note: database.ID is of int type. I was following the article at: http://www.sql-server-helper.com/functions

Oracle EXECUTE IMMEDIATE into a cursor

由 拜拜、爱过 提交于 2019-12-01 04:34:22
I have a stored procedure which used the EXECUTE IMMEDIATE command to execute a very long string. How do I support a very long string and return the data into a refcursor? Assuming that your SQL is not longer than 32K (as @Tony Andrews hinted at), you should be able to use something like this: declare SQL_Text varchar2(32760) := 'select * from dual'; --your query goes here cur sys_refcursor; begin open cur for SQL_Text; end; When working with Ref Cursors, open-for can be used directly, instead of execute immediate . 来源： https://stackoverflow.com/questions/4714163/oracle-execute-immediate-into

Using dynamic SQL in an OLE DB source in SSIS 2012

由 こ雲淡風輕ζ 提交于 2019-12-01 03:02:55
问题 I have a stored proc as the SQL command text, which is getting passed a parameter that contains a table name. The proc then returns data from that table. I cannot call the table directly as the OLE DB source because some business logic needs to happen to the result set in the proc. In SQL 2008 this worked fine. In an upgraded 2012 package I get "The metadata could not be determined because ... contains dynamic SQL. Consider using the WITH RESULT SETS clause to explicitly describe the result

MySQL join tables where table name is a field of another table

问题 I have 5 tables. One primary and 4 additional (they have different columns). objects obj_mobiles obj_tablets obj_computers Here is the structure of my main table (objects). ID | type | name | etc... So what I want to do is to join objects with other (obj_mobiles,obj_tablets,...) tables, depending on type field. I know that I should use dynamic SQL. But I can't make procedure. I think it should look like something like this. SELECT objects.type into @tbl FROM objects; PREPARE stmnt FROM

Dynamic SQL - Check syntax and semantics

由 帅比萌擦擦* 提交于 2019-12-01 00:33:52
With Oracle dynamic SQL one is able to execute a string containing a SQL statement. e.g. l_stmt := 'select count(*) from tab1'; execute immediate l_stmt; Is it possible to not execute l_stmt but check that the syntax and semantics is correct programmitically? EXPLAIN PLAN will check the syntax and semantics of almost all types of SQL statements. And unlike DBMS_SQL.PARSE it will not implicitly execute anything. The point of the explain plan is to show how Oracle will execute a statement. As a side-effect of generating the plan it must also check syntax, privileges, and generally do everything
