Question

I have a problem with my stored procedure

ALTER PROCEDURE [dbo].[TIGER_CREATE_RUNTIME_TABLE](@NOMBRE_TABLA varchar(100))
AS
    DECLARE @SQLQUERY1 AS NVARCHAR(600)
BEGIN
    SET @SQLQUERY1 = 'CREATE TABLE '+@NOMBRE_TABLA + '(
    SEGMENTO varchar(200) NULL,
    TCNFOL varchar(200) NOT NULL,
    TCCOPL_A varchar(200) NULL,
    ID_LIN_NEG varchar(200) NULL,
    TIP_LIN varchar(200) NULL,
    MON_ID_MONEDA varchar(200) NULL,
    LINEAS_FACT varchar(200) NULL,
    CF_VOZ varchar(200) NULL,
    CF_DATOS varchar(200) NULL,
    ADIC_MINS varchar(200) NULL,
    ADIC_LDN varchar(200) NULL,
    ADIC_LDI varchar(200) NULL,
    ADIC_SMS varchar(200) NULL,
    PAQ_SMS varchar(200) NULL,
    ADIC_DATOS varchar(200) NULL,
    OTROS varchar(200) NULL,
    SUB_TOT varchar(200) NULL,
    PERIODO_ANALISIS varchar(200) NULL,
    PERIODO_ALTA varchar(200) NULL,
    CATEGORIA varchar(200) NULL,
    RUC varchar(200) NULL)'

    EXEC sp_ExecuteSql @SQLQUERY1
END

As you can see, I’m using dynamic SQL, but there is an error while I execute it.

Incorrect syntax near ‘varch’.

Is there any wrong with dynamic SQL? Thanks for a while.

I would change your @sqlquery1 to varchar(max), I think you are hitting the character limit when you add your table name:

 DECLARE @SQLQUERY1 AS NVARCHAR(max)

You have your limit of your query string set to 600 but when you add in a table name of up to varchar(100) you are most likely going over the limit.

If you run just the following with no table name the len is 726 characters:

DECLARE @SQLQUERY1 AS NVARCHAR(max)

SET @SQLQUERY1 = 'CREATE TABLE (
    SEGMENTO varchar(200) NULL,
    TCNFOL varchar(200) NOT NULL,
    TCCOPL_A varchar(200) NULL,
    ID_LIN_NEG varchar(200) NULL,
    TIP_LIN varchar(200) NULL,
    MON_ID_MONEDA varchar(200) NULL,
    LINEAS_FACT varchar(200) NULL,
    CF_VOZ varchar(200) NULL,
    CF_DATOS varchar(200) NULL,
    ADIC_MINS varchar(200) NULL,
    ADIC_LDN varchar(200) NULL,
    ADIC_LDI varchar(200) NULL,
    ADIC_SMS varchar(200) NULL,
    PAQ_SMS varchar(200) NULL,
    ADIC_DATOS varchar(200) NULL,
    OTROS varchar(200) NULL,
    SUB_TOT varchar(200) NULL,
    PERIODO_ANALISIS varchar(200) NULL,
    PERIODO_ALTA varchar(200) NULL,
    CATEGORIA varchar(200) NULL,
    RUC varchar(200) NULL)'

select LEN(@sqlquery1)

If you leave your query string at a length of 600 your create table statement will be cut off and will generate an error.
