SQLCMD Mode Script Executing on Multiple Schemas

Hi

Put the client and schema information into a temp or in memory table
Loop through the table by taking the first record execute some dynamic sql that takes the values from the record then   delete the record  it when you are done executing code something like this:

DECLARE @ClientSchema TABLE( client varchar(50), clientSchema varchar(50))
DECLARE @someRandomFilter VARCHAR(50) = 'Filter'

Insert into @ClientSchema(client,clientSchema)
SELECT client,clientSchema from clientSchemaTable

DECLARE @client varchar(50)
DECLARE @clientSchema VARCHAR(50)
DECLARE @sql NVARCHAR(MAX)

SELECT TOP 1 @client = client, @clientSchema = clientSchema FROM clientSchemaTable

WHILE @clientSchema IS NOT NULL
BEGIN
	SET @sql = 'DELETE FROM ' + @schema + '.TableName where column1 = ' + @someRandomFilter

	exec(@pivotSql)


	DELETE FROM @ClientSchema where client = @client and clientSchema = @clientSchema

	SET @client = NULLSET @ClientSchema = NULL
	SELECT TOP 1 @client = client, @clientSchema = clientSchema FROM clientSchemaTable
END

Hi Marcus,

thank you for your help.  So if I'm understanding you correctly, all the scripts that are doing some altering of tables or data need to be change to dynamic sql?

Here is an example of what is in this db update script:

DECLARE @GUID UNIQUEIDENTIFIER
------------------------------------------
SET @GUID = '{12D4BEEC-2825-4949-A356-48716F0142C8}'

------------------------------------------
IF (SELECT COUNT(*) FROM [$(SchemaName)].tblSchemaEvolution WHERE ChangeID = @GUID) = 0
BEGIN

PRINT 'Applying update ' + convert(nvarchar(max), @GUID)

UPDATE [$(SchemaName)].DealCustomMetaData SET DefaultLabel='Employees' WHERE FieldName='SR_Employees'
UPDATE [$(SchemaName)].DealCustomMetaData SET DefaultLabel='Locations' WHERE FieldName='SR_Locations'

INSERT INTO [$(SchemaName)].tblSchemaEvolution (ChangeID) VALUES (@GUID)

END
GO

I suggest that you create a stored procedure and put your update code in there. and then call the stored procedure from a scheduling tool or SSIS or whichever automation mechanism your are using

It could look like the following.

CREATE PROCEDURE dbo.UpdateProcedure
@guid VARCHAR(50)
AS
BEGIN
	DECLARE @ClientSchema TABLE (client VARCHAR(50),clientSchema VARCHAR(50))
	INSERT INTO @ClientSchema(client,clientSchema)
	SELECT client,clientSchema from clientSchemaTable

	DECLARE @client varchar(50)
	DECLARE @clientSchema VARCHAR(50)
	DECLARE @sql NVARCHAR(MAX)

	SELECT TOP 1 @client = client, @clientSchema = clientSchema FROM clientSchemaTable

	WHILE @clientSchema IS NOT NULL
	BEGIN

		SET @sql = '

		UPDATE [' + @clientSchema + '].DealCustomMetaData SET DefaultLabel=''Employees'' WHERE FieldName=''SR_Employees''
	
		UPDATE [' + @clientSchema +'].DealCustomMetaData SET DefaultLabel=''Locations'' WHERE FieldName=''SR_Locations''

		INSERT INTO [' + @clientSchema + '].tblSchemaEvolution (ChangeID) VALUES(''' + @guid + ''')'

		exec(@sql)


		DELETE FROM @ClientSchema where client = @client and clientSchema = @clientSchema

		SET @client = NULL
                SET @ClientSchema = NULL

		SELECT TOP 1 @client = client, @clientSchema = clientSchema FROM clientSchemaTable
	END
END

ok, so dynamic sql is the only option.  It is a very large script file and converting it to dynamic sql will definitely take a lot of time.

Thanks for your help.
