We have a vendor specific application that has 100's of tables and most of them have a column called Company_Code and within that column is stored a value for each company. Is it possible to search the entire database where COMPANY_CODE = 'TST' and return those values?
This should do the trick:
DECLARE #Value varchar(100) = 'TST';
DECLARE #script varchar(1000);
CREATE TABLE ##Results (TableName VARCHAR(100) , ValueCount INT);
DECLARE db_cursor CURSOR FOR
WITH cte AS
(
SELECT o.NAME AS TableName , c.name As ColumnName
FROM sys.sysobjects o
JOIN sys.syscolumns c on o.id = c.id
WHERE c.name = 'COMPANY_CODE '
)
SELECT 'INSERT INTO ##Results (TableName , ValueCount) SELECT ''' + TableName + ''' , COUNT(*) FROM ' + TableName + ' WHERE ' + ColumnName + ' = ''' + #Value + '''' AS Script
FROM cte;
OPEN db_cursor
FETCH NEXT FROM db_cursor INTO #script
WHILE ##FETCH_STATUS = 0
BEGIN
PRINT #script;
EXEC (#Script);
FETCH NEXT FROM db_cursor INTO #script
END
CLOSE db_cursor
DEALLOCATE db_cursor
SELECT * FROM ##Results WHERE ValueCount > 0
The script below shows an example query for data that have been converted from lower case, but it only changed the data on one column in the table.
Use MYF601T
Go
UPDATE ROAD_LINE
SET NAM = UPPER(NAM)
However, the following script that I'm trying to write is to convert all on all columns on all tables, but the result generated with errors.
Use MYF601T
Go
UPDATE INFORMATION_SCHEMA.TABLES
SET INFORMATION_SCHEMA.TABLES.TABLE_SCHEMA = UPPER(INFORMATION_SCHEMA.TABLES.TABLE_SCHEMA
How to do this for all tables and all columns inside?
If for whather reasons you want to convert your tables names to Upper case, you can:
use a cursor that will select the tables you want to rename
loop through the table list
rename it using sp_rename or update it
Note that you have to update the Select in the cursor to suit your needs (select column or table name you want, ...)
This will rename tables:
declare #TABLE_NAME sysname, #TABLE_SCHEMA sysname
declare #TABLE sysname, #newName sysname
declare table_cursor Cursor
For Select TABLE_NAME, TABLE_SCHEMA From INFORMATION_SCHEMA.TABLES Where TABLE_NAME like 'xyz%' -- and TABLE_SCHEMA like ...
open table_cursor
Fetch Next From table_cursor Into #TABLE_NAME, #TABLE_SCHEMA;
While ##FETCH_STATUS = 0
Begin
Set #TABLE = quotename(UPPER(#TABLE_SCHEMA)) + '.' + quotename(UPPER(#TABLE_NAME))
Set #newName = UPPER(#TABLE_NAME)
print 'rename ' + #TABLE + ' to ' + #newName
-- uncomment next like if you really want to rename them
--exec sp_rename #TABLE, #newName
Fetch Next From table_cursor Into #TABLE_NAME, #TABLE_SCHEMA;
End
Close table_cursor
Deallocate table_cursor
If you want to update all columns xyz in table zyx, you can use this:
declare #TABLE_NAME sysname, #TABLE_SCHEMA sysname, #COLUMN_NAME sysname
declare #TABLE sysname, #sql nvarchar(max)
declare table_cursor Cursor
For Select TABLE_NAME, TABLE_SCHEMA, COLUMN_NAME From INFORMATION_SCHEMA.COLUMNS
Where COLUMN_NAME like 'xxx' -- and data_type '' ... and TABLE_NAME like 'xyz%' ... and TABLE_SCHEMA like ...
open table_cursor
Fetch Next From table_cursor Into #TABLE_NAME, #TABLE_SCHEMA, #COLUMN_NAME;
While ##FETCH_STATUS = 0
Begin
Set #TABLE = quotename(#TABLE_SCHEMA) + '.' + quotename(#TABLE_NAME)
set #sql = 'Update ' + #TABLE + ' set ' + #COLUMN_NAME + ' = UPPER(' + #COLUMN_NAME + ')'
print #sql
-- uncomment next like if you really want to execute them
--exec sp_executesql #sql
Fetch Next From table_cursor Into #TABLE_NAME, #TABLE_SCHEMA, #COLUMN_NAME;
End
Close table_cursor
Deallocate table_cursor
Use a dynamic query to update all the column content to upper case.
Query
declare #query varchar(max)
select #query =
stuff
(
(
select ';update ' + table_name + ' ' +
'set ' + column_name + ' = upper(' + column_name + ')'
from information_schema.columns
where table_name = 'ROAD_LINE'
order by table_name,column_name
for xml path('')
)
, 1, 1, '')
execute(#query);
I am looking for a script which finds and replaces all fields of type string within a DB with specified text.
The script would for example take the following parameters:
Search for: null
Replace with: empty-string
The primary string data types in SQL Server: Varchar, NVarchar, Text.
This script would then comb through all string based table data and look for in this case null and replace it with a empty string.
Ok I've put together the following code in the meantime.
-- Specify 'dbo' for all tables
DECLARE #schemaName VARCHAR(5) = 'dbo'
BEGIN
DECLARE #tableName VARCHAR(255) -- table name
DECLARE #tableID INT -- table id (aka syst.table.object_id)
DECLARE table_cursor CURSOR FOR
SELECT T.object_id AS TableID, T.name AS TableName FROM sys.tables T
INNER JOIN sys.schemas S ON S.schema_id = T.schema_id
WHERE S.name = #schemaName
OPEN table_cursor
FETCH NEXT FROM table_cursor INTO #tableID, #tableName
WHILE ##FETCH_STATUS = 0
BEGIN
-- construct each tables queries
DECLARE #totalColumnsFound INT = (SELECT COUNT(*) FROM sys.columns C WHERE OBJECT_ID = #tableID

AND (C.system_type_id = 35 OR c.system_type_id = 231))
IF (#totalColumnsFound > 0)
BEGIN
DECLARE #tableUpdateQuery VARCHAR(MAX) = 'update ' + #schemaName + '.' + #tableName + ' set ';

OPEN column_cursor
FETCH NEXT FROM column_cursor INTO #columnName
WHILE ##FETCH_STATUS = 0
BEGIN
-- construct the columns for the update query, piece by piece.
-- This is also where you can apply your logic for how to handle the string update.
-- I am trimming string and updating nulls to empty strings here.
SET #tableUpdateQuery = #tableUpdateQuery + ' ' + #columnName + ' = ltrim(rtrim(isnull(' + #columnName + ',''''))),'
FETCH NEXT FROM column_cursor INTO #columnName
END
CLOSE column_cursor
DEALLOCATE column_cursor

As a usage example:
EXEC UPDATE_ALL_COLUMNS '%temp%', 'dbo', '', NULL
Parameters:
#TableNameSearchFilter - this will be used with the LIKE operator to find all the tables from your database whose names that match this value;
#TableSchema - the schema of the table (usually dbo)
#TestValue - the value to search for in ALL of the columns (and rows) of each found table;
#NewValue - the value to replace #TestValue with. Can also be NULL.
Explanation:
The EXEC statement will find ALL tables whose names contain the word 'temp', on the 'dbo' schema of your database, then search for the value '' (empty string) in ALL columns of ALL of the found tables, then replace this value with a NULL.
Obviously, if you have long(er) column/table names or the update value, make sure to update the limits on the parameters.
Make sure to first comment the last line (EXEC (#SQL)) and uncomment the lines with PRINT, just to get an idea for what the procedure does and how the final statements look like.
This is not going to work (most likely) if you want to search for the NULL value (i.e. to have #TestValue as NULL). Nevertheless, it can be easily changed to accomplish this as well, by replacing the equal sign from the WHERE clause (in the dynamic query) with IS NULL and removing the rest of the line, when #TestValue IS NULL.
Can be easily adapted to search for columns of only certain types (like VARCHAR etc).
The procedure accounts for inserting NULL values, and will only do so in NULLABLE columns.
I want to update some rows which be include some null fields.
How can I update these rows in SQL Server?
I am asking because a rows has got 180 fields. :)
Please help me.
You can use dynamic SQL to generate a script to run. The following will probably need tweaking for you to exclude columns that you don't want to update etc.
DECLARE #TableName nvarchar(500) = '[dbo].[T]'
DECLARE #DynSql nvarchar(max)
SELECT #DynSql = ISNULL(#DynSql+',','') + QUOTENAME(name) + '= ISNULL(' + QUOTENAME(name) + ',0)'
FROM sys.columns
WHERE object_id = OBJECT_ID(#TableName)
SET #DynSql = 'UPDATE ' + #TableName + 'SET ' + #DynSql
PRINT #DynSql
--EXEC(#DynSql)
I think I understand what you are asking. This will generate an update statement for each column in your table that will set it's value to 0 if it's value is null.
declare #tableName nvarchar(100)
declare #querys varchar(max)
set #querys = ''
set #tableName = 'YOUR TABLE NAME HERE'
select #querys = #querys + 'update ' + #tableName + ' set ' +
QUOTENAME(t.[name]) + '=0 where ' + QUOTENAME(t.[name]) + ' is null;'
from (SELECT [name] FROM syscolumns
WHERE id = (SELECT id
FROM sysobjects
WHERE type = 'U'
AND [NAME] = #tableName))t
select #querys
execute sp_executesql #sqlQuery
Well It is an old post, but I recently had this problem and wanted a dynamic SQL query using the above solution that performed the update depending on column types.
USE [YOUR DATABASE]

Here is my script grab from net

The above query will display column names that are null values. But I need to save them into another variable with comma separated values.
Thanks in advance.
