Are there any free tools for scripting MSSQL table data? I'll gladly write one, but am hoping it's been done, and the app matured a bit before/
Here are some scripts I wrote for reverse engineering SQL server schemas. They may be of some use. Also, as a general interest they give some examples of how to get various bits of information out of the data dictionary. I've added an MIT license below to make permission-to-use explicit and for some basic no-implicit-warranty CYA. Enjoy.

-- Script to generate table, index, pk, view and fk definitions from

-- partition schemes) but it does do defaults and computed columns

-- Run the script with 'results to text' and cut/paste the output into

Microsoft SQL Server Database Publishing Wizard is a nice GUI that can script out the structure / data / Procs of a SQL Server 2000/2005 db.

Hope this helps
A quick google and hop pointed me to a Stored proc that should be able to help you. Look at My code library more specifically the file generate_inserts.txt to see if it can help you.
Not really a tool, but the start of one! :)
For loading and unloading table data you could also use bcp, Integration Services or BULK INSERT (for the loading portion). This article describes a method to invoke bcp from within a stored procedure.
TOAD for Oracle can do it, so I suspect TOAD for SQL Server will be able to too.

Maybe you can try this SQL Server script:

From sys.sql_modules m
inner join sys.objects o on m.object_id = o.object_id
where m.definition like '%' + #sp_name +'%'
and o.type = 'P'

I have an application on vb.net that use a Sql server Database.
I'm using Entity Framework 6.1
The database has a lot's of tables (100+)
-On some tables there's a field "DelDate" (Date)
-On some tables there's a field "DelChilds" (Bit)
Is there a short way to do these operations :
1) Delete all records from all tables that have the DelDate= "01/01/2014"
2) Update the "DelChilds" field on all the records ( for example set to True )
Thank you !
You can write a Dynamic Query using sys.column and sys.tables and execute them in a batch .
You can call Stored Procedure to achieve this functionality using entity framework .
Procedure Code
Create Procedure UpdateDelete #date Date = '01/01/2014'
AS
Begin
Declare #DelQuery Nvarchar(Max),#updatequery Nvarchar(Max),
select #DelQuery = Stuff( (
select ' Delete from ' + t.name + ' where DelDate = ''' + Convert ( varchar,#date,110) + ''';' from sys.columns C JOIN sys.tables t on c.object_id = t.object_id
where C.name = 'DelDate' for XMl Path('')),1,1,'')
select #DelQuery
Exec sp_executeSQL #DelQuery
select #updatequery = Stuff( (
select ' UPDATE ' + t.name + ' SET DelChilds = 1 ;' from sys.columns C JOIN sys.tables t on c.object_id = t.object_id
where C.name = 'DelChilds' for XMl Path('')),1,1,'')
--select #updatequery
Exec sp_executeSQL #updatequery
END
For DelDate
select 'DELETE FROM ' + t.name + ' WHERE DelDate = ''01/01/2014'' ' + Char(13) + 'GO ' from sys.columns C JOIN sys.tables t on c.object_id = t.object_id
where C.name = 'DelDate'
For Delchilds
select 'UPDATE ' + t.name + ' SET DelChilds = 1 ' + Char(13) + 'GO ' from sys.columns C JOIN sys.tables t on c.object_id = t.object_id
where C.name = 'DelChilds'
SELECT DateTime, Skill, Name, TimeZone, ID, User, Employee, Leader
FROM t_Agent_Skill_Group_Half_Hour AS t
I need to view the table structure in a query.
For SQL Server, if using a newer version, you can use
select *
from INFORMATION_SCHEMA.COLUMNS
where TABLE_NAME='tableName'
There are different ways to get the schema. Using ADO.NET, you can use the schema methods. Use the DbConnection's GetSchema method or the DataReader'sGetSchemaTable method.
Provided that you have a reader for the for the query, you can do something like this:
using(DbCommand cmd = ...)
using(var reader = cmd.ExecuteReader())
{
var schema = reader.GetSchemaTable();
foreach(DataRow row in schema.Rows)
{
Debug.WriteLine(row["ColumnName"] + " - " + row["DataTypeName"])
}
}
See this article for further details.

On SQL Server 2012, you can use the following stored procedure:
sp_columns '<table name>'
For example, given a database table named users:
sp_columns 'users'
In SQL Server, you can use this query:
USE Database_name
SELECT *
FROM INFORMATION_SCHEMA.COLUMNS
WHERE TABLE_NAME='Table_Name';
And do not forget to replace Database_name and Table_name with the exact names of your database and table names.
For recent versions of SQL Server Management Studio Write the in a query editor and Do "Alt" + "F1"
Try this query:
select *
from (SELECT TABLE_SCHEMA
FROM INFORMATION_SCHEMA.TABLES
WHERE TABLE_NAME='brands')[.brands];
To print a schema, I use jade and do an export to a file of the database then bring it into word to format and print
I was trying 'DESC table_name' but then this worked for me in psql:
select *
from INFORMATION_SCHEMA.COLUMNS
where TABLE_NAME='table_name';
Another way is,
mysql > SHOW CREATE TABLE my_db.my_table;
You should get the table name and create table sql
I have a local db which has FOREIGN KEY constraints.
The live version of this websites DB, does not have any of these FOREIGN KEY constraints.
How can I "copy/paste", import/export ONLY the FOREIGN KEY constraints from one db to the other?
I do NOT want to copy any data, only the constraints.
Thanks
You could use this script I found at http://www.siusic.com/wphchen/how-to-script-out-all-the-foreign-keys-of-a-table-106.html. Replace tablename1 and tablename2 with the list of tables you wish to get the foreign keys for.

I needed to do something similar, where I needed the same foreign keys on multiple servers, except some had already been added. So I added a "IF NOT EXISTS" check to the beginning of the creation statements:

AND parent_object_id = OBJECT_ID(''' + QUOTENAME(cs.name) + '.' + QUOTENAME(ct.name) +''')
)

If you do not want the "IF NOT EXISTS" checks (they really shouldn't matter), just delete the top 5 lines and add "SELECT N' " right before the "BEGIN", like this:
SELECT N'BEGIN
ALTER TABLE '
+ QUOTENAME(cs.name) + '.' + QUOTENAME(ct.name)

How do I query the database for all types of constraints such as Primary Key,Foreign Key, Unique Key, and Default Constraint, and rename its system generate name to a name in following format:
PK_ColumnName1_ColumnName2
FK_ColumnName1
UK_ColumnName1_ColumnName2
DF_ColumnName1
SELECT tbl.name TableName, col.name ColName, ck.name ConstraintName, ck.definition ConstraintDefinition ,' exec sp_rename [' +ck.name + '] , [DF_' + col.name + ']' SqlQuery
FROM sys.default_constraints ck
INNER JOIN sys.tables tbl
on ck.parent_object_id = tbl.object_id
INNER JOIN sys.columns col
on tbl.object_id = col.object_id
and ck.parent_column_id = col.column_id
This is for default constraints
use sys.key_constraints
ans sys.foreign_keys
The following code is a little more detailed and it too is specific to default constraints.
select quotename(s.name) + '.' + quotename(o.name) as table_name,
dc.name as default_name,
'DF_' + o.name + '_' + c.name as new_default_name,
'execute sp_rename ''' + quotename(s.name) + '.' + dc.name + ''', ''' + 'DF_' + o.name + '_' + c.name + ''' , ''OBJECT'' -- ' + s.name + '.' + o.name + '' as rename_script
from sys.default_constraints as dc
join sys.objects as o
join sys.schemas as s
on o.schema_id = s.schema_id
on o.object_id = dc.parent_object_id
join sys.columns as c
on o.object_id = c.object_id
and c.column_id = dc.parent_column_id
where dc.name like 'DF[_][_]%[_][_]%[_][_]%' -- DF__AlertType__Creat__10F7245D
and o.type = 'u'
and o.is_ms_shipped = 0
order by s.name,
o.name
