Question

I’m looking for a way to automatically create a 1:1 view per table for a bunch of tables.
Since there are plenty of tables for which I need a view, it would be time-consuming to create them manually.

Perfect scenario would be a query creating the create view queries for each table given at once.

This should do the trick for the current database. It’s still dynamic SQL, but… Note that it does not check to see if the views already exist. You can add a WHERE clause to the cursor query to limit the tables – WHERE t.name = '...' or WHERE t.name IN ('...','....').

DECLARE @SchemaName sysname
DECLARE @SchemaQualifiedTableName sysname
DECLARE @TableName sysname
DECLARE @ColumnCount INT
DECLARE @ColumnID INT
DECLARE @SelectColumn NVARCHAR(500)
DECLARE @sql NVARCHAR(max) = ''

DECLARE QUERYINFO CURSOR FOR
    SELECT
        SCHEMA_NAME(t.schema_id) AS SchemaName,
        '[' + SCHEMA_NAME(t.schema_id) + '].[' + t.name + ']' AS SchemaQualifiedTableName,
        t.name AS TableName,
        ccount.ColumnCount,
        c.column_id AS ColumnID,
        CASE WHEN c.column_id <> ccount.ColumnCount
                THEN c.name + ', '
             ELSE c.name
             END AS SelectColumn
    FROM sys.tables t
    INNER JOIN sys.columns c ON t.object_id=c.object_id
    INNER JOIN (
        SELECT object_id,COUNT(*) AS ColumnCount
        FROM sys.columns
        GROUP BY object_id
    ) ccount ON t.object_id = ccount.object_id
    ORDER BY t.Name,c.column_id

OPEN QUERYINFO
FETCH NEXT FROM QUERYINFO INTO @SchemaName,@SchemaQualifiedTableName,@TableName,@ColumnCount,@ColumnID,@SelectColumn
WHILE @@FETCH_STATUS = 0
BEGIN
    IF @ColumnID = 1
    BEGIN
        SET @sql = 'CREATE VIEW [' + @SchemaName + '].v_' + @TableName + ' AS SELECT ' + @SelectColumn
    END
    ELSE
    BEGIN
        SET @sql = @sql + @SelectColumn
    END  
  
    IF @ColumnID = @ColumnCount
    BEGIN
        SET @sql = @sql + ' FROM ' + @SchemaQualifiedTableName
        EXEC sys.sp_executesql @sql
        SET @sql = ''
    END 
    
    FETCH NEXT FROM QUERYINFO INTO @SchemaName,@SchemaQualifiedTableName,@TableName,@ColumnCount,@ColumnID,@SelectColumn
END

CLOSE QUERYINFO
DEALLOCATE QUERYINFO
