Question

在第一个存储过程中，testList是用户定义的表类型

CREATE PROCEDURE [working].[test1] (@input1 int, @input2 testList READONLY) AS
BEGIN

// do some working

END
GO

CREATE PROCEDURE [working].[test2] (@input3 int, @input4 char) AS
BEGIN

// How can i convert char input4 to user defined table input testList 
// I want to do that conversion because ,here i want to call stored procedure test1

EXEC [working].[test1] @input1 = @input3 , @input2 = CAST(@input4 AS testList);

// is this correct way to call ?

END
GO

Answer 1

CREATE PROCEDURE [working].[test2] 
   @input3 int, 
   @input4 CHAR(N)
AS
BEGIN
   SET NOCOUNT ON;

-- Declare a table variable of testList type

DECLARE @Table_Var AS testList;

--  Populate the table variable with value passed to @input4  

INSERT INTO @Table_Var (ColumnName)
VALUES (@input4)


-- Now pass this table variable to your procedure 

EXEC [working].[test1] @input1 = @input3 
                     , @input2 = @Table_Var

END
GO

将char输入转换为用户定义的表类型并从其他存储过程调用一个存储过程？
