How to execute store procedure for another DB?

You can fully qualify both tables and stored procedures. In other words you can do this:

UPDATE [OtherDB].[Schema].[targetTable] SET ...

It appears you are doing this in your proc already.

You can also EXEC a stored procedure using the Fully Qualified name - e.g.

EXEC [OtherDB].[dbo].[usp_TrimAndLowerCaseVarcharFields]

Honestly, your proc looks fine, are you receiving any error messages? If so please post them. Also, make sure your user has access to the other DB.

The table name in the query you used is wrong, it is looking up into same database, but you do need to look up from different database. So the query will be as below:

SELECT @sSql = @sSql + COLUMN_NAME + ' = LOWER(RTRIM(' + COLUMN_NAME + ')), ' FROM [TargetDB].INFORMATION_SCHEMA.COLUMNS WHERE DATA_TYPE = 'varchar'AND TABLE_CATALOG = @DatabaseAND TABLE_SCHEMA = @TableSchemaAND TABLE_NAME = @TableName-- [TargetDB] = @Database

The TargetDB will be same as your passing database (@Database)

If you want to use [TargetDB] dynamically then you need to generate sql(@sSql) and the execute the sql string.

In this case I sugest to use the 2 sp's in SQL Server:

• sp_MSforeachtable

• sp_MSforeachdb

for more information, please read the article in here. hope this help.

exec @RETURN_VALUE=sp_MSforeachtable @command1, @replacechar, @command2,   @command3, @whereand, @precommand, @postcommandexec @RETURN_VALUE = sp_MSforeachdb @command1, @replacechar,   @command2, @command3, @precommand, @postcommand

Complete script:

declare @DatabaseName varchar(max), @DatabaseCharParam nchar(1) declare @TableSchema varchar(max) declare @TableName varchar(max), @TableCharParam nchar(1) set @DatabaseName='DATABASENAME'; set @DatabaseCharParam='?'set @TableSchema='dbo'set @TableName='TABLENAME'; set @TableCharParam='$' -- Exemple Script to execute in each table in each database -- Create first part of a statement to update all columns that have type varchar    DECLARE @sSql VARCHAR(MAX)    set @sSql=''    SELECT @sSql = isnull(@sSql,'') + COLUMN_NAME + ' = LOWER(RTRIM(' + COLUMN_NAME + ')),'     FROM INFORMATION_SCHEMA.COLUMNS     WHERE DATA_TYPE = 'varchar'    AND TABLE_CATALOG = @DatabaseName    AND TABLE_SCHEMA = @TableSchema    AND TABLE_NAME = @TableNamedeclare @EachTablecmd1 varchar(2000)--Prepare @EachTablecmd1 the script to execution in each table using sp_MSforeachtable (ATENTION: @Command1 are limited to varchar(2000) )    --in sp_MSforeachtable @TableCharParam will be subtituted with owner i.e:[dbo].[TABLENAME]set @sSql='update '+@TableCharParam+' set '+ left(@sSql,LEN(@sSql)-1) set @EachTablecmd1='if '''''+ @TableCharParam +'''''=''''['+@TableSchema+'].['+@TableName+']'''' '+@sSql    --i.e.: if 'table1'='table1' update table1 set column1=LOWER(RTRIM(column1)),....-- the @sSql for each table in a databaseset @sSql ='exec sp_MSforeachtable @command1='''+@EachTablecmd1+''' ,@replacechar='''+@TableCharParam+''''declare @EachBDcmd1 varchar(2000)--Prepare the execution to each database using sp_MSforeachdb (ATENTION: @Command1 are limited to varchar(2000) )set @EachBDcmd1='if '''+@DatabaseCharParam+'''='''+@DatabaseName+''' '+ @sSql--print @EachBDcmd1exec sp_MSforeachdb @command1=@EachBDcmd1,@replacechar=@DatabaseCharParam
