SQL server script for generating script for table - sql

Question

I have following situation: I'm working on project where data base contains hundreds of tables, and very often I know what table I need to generate script for, but finding it in the list of all tables takes a lot of time. I would like to know, is there a way to write script which will generate script for table. Since I already know table name, it's easier for me just to type it than search it in huge list of similar names.

Answer 1

Yes, you can definitely write your own procedure to generate scripts for a given table name which will be provided as parameter. In my example, I am passing 'dbo.TABLE1' as a parameter to this query:
(You can wrap this into a stored procedure, of course)
DECLARE
#object_name SYSNAME = 'dbo.TABLE1'
, #object_id INT = object_id('dbo.TABLE1')
, #SQL NVARCHAR(MAX)
SELECT
#object_name = '[' + OBJECT_SCHEMA_NAME(o.[object_id]) + '].[' + OBJECT_NAME([object_id]) + ']'
, #object_id = [object_id]
FROM (SELECT [object_id] = #object_id) o
SELECT #SQL = 'CREATE TABLE ' + #object_name + CHAR(13) + '(' + CHAR(13) + STUFF((
SELECT CHAR(13) + ' , [' + c.name + '] ' +
CASE WHEN c.is_computed = 1
THEN 'AS ' + OBJECT_DEFINITION(c.[object_id], c.column_id)
ELSE
CASE WHEN c.system_type_id != c.user_type_id
THEN '[' + SCHEMA_NAME(tp.[schema_id]) + '].[' + tp.name + ']'
ELSE '[' + UPPER(tp.name) + ']'
END +
CASE
WHEN tp.name IN ('varchar', 'char', 'varbinary', 'binary')
THEN '(' + CASE WHEN c.max_length = -1
THEN 'MAX'
ELSE CAST(c.max_length AS VARCHAR(5))
END + ')'
WHEN tp.name IN ('nvarchar', 'nchar')
THEN '(' + CASE WHEN c.max_length = -1
THEN 'MAX'
ELSE CAST(c.max_length / 2 AS VARCHAR(5))
END + ')'
WHEN tp.name IN ('datetime2', 'time2', 'datetimeoffset')
THEN '(' + CAST(c.scale AS VARCHAR(5)) + ')'
WHEN tp.name = 'decimal'
THEN '(' + CAST(c.[precision] AS VARCHAR(5)) + ',' + CAST(c.scale AS VARCHAR(5)) + ')'
ELSE ''
END +
CASE WHEN c.collation_name IS NOT NULL AND c.system_type_id = c.user_type_id
THEN ' COLLATE ' + c.collation_name
ELSE ''
END +
CASE WHEN c.is_nullable = 1
THEN ' NULL'
ELSE ' NOT NULL'
END +
CASE WHEN c.default_object_id != 0
THEN ' CONSTRAINT [' + OBJECT_NAME(c.default_object_id) + ']' +
' DEFAULT ' + OBJECT_DEFINITION(c.default_object_id)
ELSE ''
END +
CASE WHEN cc.[object_id] IS NOT NULL
THEN ' CONSTRAINT [' + cc.name + '] CHECK ' + cc.[definition]
ELSE ''
END +
CASE WHEN c.is_identity = 1
THEN ' IDENTITY(' + CAST(IDENTITYPROPERTY(c.[object_id], 'SeedValue') AS VARCHAR(5)) + ',' +
CAST(IDENTITYPROPERTY(c.[object_id], 'IncrementValue') AS VARCHAR(5)) + ')'
ELSE ''
END
END
FROM sys.columns c WITH(NOLOCK)
JOIN sys.types tp WITH(NOLOCK) ON c.user_type_id = tp.user_type_id
LEFT JOIN sys.check_constraints cc WITH(NOLOCK)
ON c.[object_id] = cc.parent_object_id
AND cc.parent_column_id = c.column_id
WHERE c.[object_id] = #object_id
ORDER BY c.column_id
FOR XML PATH(''), TYPE).value('.', 'NVARCHAR(MAX)'), 1, 7, ' ') +
ISNULL((SELECT '
, CONSTRAINT [' + i.name + '] PRIMARY KEY ' +
CASE WHEN i.index_id = 1
THEN 'CLUSTERED'
ELSE 'NONCLUSTERED'
END +' (' + (
SELECT STUFF(CAST((
SELECT ', [' + COL_NAME(ic.[object_id], ic.column_id) + ']' +
CASE WHEN ic.is_descending_key = 1
THEN ' DESC'
ELSE ''
END
FROM sys.index_columns ic WITH(NOLOCK)
WHERE i.[object_id] = ic.[object_id]
AND i.index_id = ic.index_id
FOR XML PATH(N''), TYPE) AS NVARCHAR(MAX)), 1, 2, '')) + ')'
FROM sys.indexes i WITH(NOLOCK)
WHERE i.[object_id] = #object_id
AND i.is_primary_key = 1), '') + CHAR(13) + ');'
SELECT #SQL

Here is a link to a stored proc code , you can add and execute by giving just the table name to get the DDL.
