    <p>I am learning how to use SQL and Stored Procedures. I know the syntax is incorrect:</p> <p>Copy data from one table into another table on another Database with a Stored Procedure. The problem is I don't know what table or what database to copy to. I want it to use parameters and not specify the columns specifically.</p> <p>I have 2 Databases (Master_db and Master_copy) and the same table structure on each DB.</p> <p>I want to quickly select a table in Master_db and copy that table's data into Master_copy table with same name. I have come up with something like this:</p> <pre><code>USE Master_DB CREATE PROCEDURE TransferData DEFINE @tableFrom, @tableTo, @databaseTo; INSERT INTO @databaseTo.dbo.@databaseTo SELECT * FROM Master_DB.dbo.@tableFrom GO; </code></pre> <hr> <p>The closest I could get was this. The problem now is that I have a Timestamp column and that rendered an error:</p> <p>"Cannot insert an explicit value into a timestamp column. Use INSERT with a column list to exclude the timestamp column, or insert a DEFAULT into the timestamp column." </p> <pre><code>USE Kenneth_Integration GO CREATE PROCEDURE TransferData @table SYSNAME ,@databaseTo SYSNAME AS DECLARE @sql NVARCHAR(MAX) SET @sql = 'DELETE FROM ' + @databaseTo + '..' + @table + ' set identity_insert ' + @databaseTo + '.dbo.' + @table + ' on INSERT INTO ' + @databaseTo + '.dbo.' + @table + ' SELECT * FROM Kenneth_Integration.dbo.' + @table EXEC sp_executesql @sql GO </code></pre> <p>How can I go around this error with this SP?</p>

    1. COHave you considered what to do if you are copying to a table that may already have some of the data you are copying? Also identity columns may well be an issue.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
