I am able to search for specific text in my views and stored procedure, but I'm not able to search through my tables at the same time.
Here is what I have:
DECLARE #cmd VARCHAR(1000),
#search_string VARCHAR(200)
CREATE TABLE #temp
(
[Database_Name] sysname,
[Schema_Name] sysname,
[Object_Name] sysname,
[Object_Type] nvarchar(60)
)
-- Set the search string
SET #search_string = 'text'
SET #cmd = 'INSERT INTO #temp SELECT DISTINCT ''?'', s.name AS Schema_Name, o.name AS Object_Name, o.type_desc FROM [?].sys.sql_modules m INNER JOIN [?].sys.objects o ON m.object_id = o.object_id INNER JOIN [?].sys.schemas s ON o.schema_id = s.schema_id WHERE m.definition Like ''%' + #search_string + '%'''
-- Uncomment the following if you have problems with your command and want to see the command
--PRINT #cmd
-- Run for every database on the server
EXEC sp_MSforeachdb #cmd
-- Retrieve your results from the temp table
SELECT *
FROM #temp
ORDER BY [Database_Name], [Object_Name], [Object_Type]
-- If you want to omit certain databases from your results, simply add
-- the appropriate WHERE clause, as in the following:
--SELECT *
--FROM #temp
--WHERE db NOT IN ('DB1', 'DB4', 'DB7')
--ORDER BY db, obj_type, obj_name
DROP TABLE #temp
Please try this query for column search
SELECT
t.[name] TableName
, c.[name] ColumnName
FROM sys.columns c
INNER JOIN sys.tables t on t.object_id = c.object_id
WHERE t.[type] = 'U'
AND c.[name] LIKE '%Text%'
Below script will get result for all the databases for both Tables and other obejcts. Hope this will help.
DECLARE #command varchar(1000)
DECLARE #SearchWord VARCHAR(20) = 'Text'
CREATE TABLE #Search (DatabaseName VARCHAR(255),SchemaName VARCHAR(50),ObjectName VARCHAR(255),ObjectType VARCHAR(50))
SET #command = 'USE ? INSERT INTO #Search
SELECT DB_NAME(), SCHEMA_NAME(t.schema_id),t.[name] TableName, ''Table'' FROM sys.columns c INNER JOIN sys.tables t on t.object_id = c.object_id WHERE t.[type] = ''U'' AND c.[name] LIKE ' + '''%' + #SearchWord + '%'''
EXEC sp_MSforeachdb #command;
SET #command = 'USE ? INSERT INTO #Search
SELECT DISTINCT DB_Name(),s.name AS Schema_Name, o.name AS Object_Name, o.type_desc FROM sys.sql_modules m INNER JOIN sys.objects o ON m.object_id = o.object_id INNER JOIN sys.schemas s ON o.schema_id = s.schema_id WHERE m.definition Like ''%' + #SearchWord + '%'''
EXEC sp_MSforeachdb #command
SELECT * FROM #Search;
DROP TABLE #Search
There is an easy way
select
object= object_name(c.id), o.name , o.type
from sys.syscomments as c
join sys.objects as o on c.id = o.object_id
where c.text like '%Id%'
All compiled objects are in sys.comments, the name changed a few times depending on the version of SQL you have, the sample is from the current version.
Now, one doesn't need to join sys.object as the TSQL is in the text column.
You can look for any string that you have used, table names, field names or code comments. the sample shows %ID% looking for all function, trigger, views procedures that have something that contains the letters ID.
You know that when clicking on an object in SSMS you can select show Dependencies right?
I want to produce a report that shows metadata about the tables and columns across databases on a server.
Ideally I would like to have the databases themselves included as a column in the report but cannot find a suitable relationship between the various sys objects on SQL Server.
So far I have:
DECLARE #R VARCHAR(50)
SET #R = 'Test1'
DECLARE #T VARCHAR(50)
SET #T = 'TESTSTUFF'
SELECT AC.[name] AS [COLUMN_NAME], T.[name] AS [TABLE_NAME], #R AS [DATABASE], '' AS [DESCRIPTION]
FROM Test1.sys.[tables] AS T
INNER JOIN Test1.sys.[all_columns] AC ON T.[object_id] = AC.[object_id] `
WHERE T.[is_ms_shipped] = 0
UNION ALL
SELECT AC.[name] AS [column_name],
T.[name] AS [table_name], #T AS [DATABASE], '' AS [DESCRIPTION]
FROM TESTSTUFF.sys.[tables] AS T
INNER JOIN TESTSTUFF.sys.[all_columns] AC ON T.[object_id] = AC.[object_id]
WHERE T.[is_ms_shipped] = 0
By making parameters of the database name, I'm introducing a high degree of maintainability that I feel is unnecessary. Ideally I'd want this as a view because it will update itself automatically each time database objects are added.
The goal is to achieve something like this:
DECLARE #D VARCHAR(50)
SET #D = (SELECT NAME FROM sys.databases WHERE name NOT IN ('master', 'tempdb', 'model', 'msdb') )
SELECT AC.[name] AS [COLUMN_NAME], T.[name] AS [TABLE_NAME], #D AS [DATABASE], '' AS [DESCRIPTION]
FROM sys.[tables] AS T
INNER JOIN sys.[all_columns] AC ON T.[object_id] = AC.[object_id]
INNER JOIN sys.databases d ON ?????
WHERE T.[is_ms_shipped] = 0
Is it possible to do this?
Although you can't use a view, you could use a script or stored procedure that generates a dynamic SQL statement. The example below generates a UNION ALL query of the catalog views of each database, each qualified with the database name.
DECLARE #SQL nvarchar(MAX);
SELECT #SQL = STUFF(
(SELECT 'UNION ALL
SELECT AC.[name] COLLATE Latin1_General_100_CI_AS_KS_WS_SC AS [COLUMN_NAME], T.[name] COLLATE Latin1_General_100_CI_AS_KS_WS_SC AS [TABLE_NAME], N''' + name + N''' AS [Database], '''' AS [DESCRIPTION]
FROM ' + QUOTENAME(name) + '.sys.[tables] AS T
INNER JOIN ' + QUOTENAME(name) + '.sys.[all_columns] AC ON T.[object_id] = AC.[object_id]
WHERE T.[is_ms_shipped] = 0 '
FROM sys.databases
WHERE name NOT IN ('master', 'tempdb', 'model', 'msdb')
FOR XML PATH, TYPE).value('.', 'nvarchar(MAX)'),1,11,'') + N';';
EXEC(#SQL);
If you use [INFORMATION_SCHEMA].[COLUMNS] instead of the sys view, it exposes the [TABLE_CATALOG] column which can be used to join to sys.databases.
You need to use
sp_MSforeachdb stored procedure to go around all DB on your server
The link between DB-Table-Schema can be made with this t-sql script
SELECT DB_NAME () as DataBaseName,
s.Name as SchemaName,
t.NAME as TableName
FROM sys.tables t
JOIN sys.indexes i ON t.object_id = i.object_id
JOIN sys.partitions p ON i.object_id = p.object_id AND i.index_id = p.index_id
JOIN sys.allocation_units a ON p.partition_id = a.container_id
JOIN sys.schemas s ON t.schema_id = s.schema_id
WHERE t.is_ms_shipped = 0 and t.NAME NOT LIKE 'dt%'
GROUP BY t.Name, s.Name, p.Rows,t.create_date
ORDER BY DB_NAME(),s.Name,t.Name
Please take a look at the code and help me on the last part, --put all together = fail !!!
I wanted to generate a string for executing sp_executesql but I'm getting an error at the end. I also tried open cursor but it error out too.
Basically I'm trying to get actual row count per column per table for all tables
because general rowcount want give you if new column added and populated.

If you want the number of rows per column per table:
DECLARE #sql NVARCHAR(MAX) = '';
SELECT #sql = #sql +
N'SELECT '''
+ t.name + ''' AS TableName, '''
+ c.name + ''' AS ColName, COUNT(' + QUOTENAME(c.name) + ') AS [RowCount] FROM '
+ QUOTENAME(t.name) + ' UNION ALL' + CHAR(10)
FROM sys.tables t
INNER JOIN sys.columns c
ON c.object_id = t.object_id
WHERE
t.type = 'U'
AND c.system_type_id <> 35
SELECT #sql = LEFT(#sql, LEN(#sql) - 11)
PRINT #sql
EXECUTE sp_executesql #sql
Not Sure what your end game is But this might help and does not use dynamic sql ...
You can put the number of columns in your original query without a CTE
This puts the col count in the original select

I need a query in Sql server 2005. I have a column name. Having that, I need to find a database name and table name. Is there any way to find it?
From SO's sister site, "StackExchange":
https://dba.stackexchange.com/questions/511/how-to-list-search-all-columns-in-a-sql-server-2008-databases
SELECT t.name AS table_name,

FROM sys.tables AS t

Possible, this script will be helpful for you -

Is there any way to count tables with no rows in my database with using T-SQL statement?
There you go... using a derived table.
SELECT * FROM
(
SELECT
[TableName] = so.name,
[RowCount] = MAX(si.rows)
FROM
sysobjects so,
sysindexes si
WHERE
so.xtype = 'U'
AND
si.id = OBJECT_ID(so.name)
GROUP BY
so.name
) sub
WHERE sub.[RowCount] = 0
I use the following:
SELECT t.NAME AS TableName, sum(p.rows) as RowCounts
FROM sys.tables t
INNER JOIN sys.indexes i
ON t.OBJECT_ID = i.object_id
INNER JOIN sys.partitions p
ON i.object_id = p.OBJECT_ID AND i.index_id = p.index_id
WHERE
i.name IS NULL AND i.index_id <= 1
GROUP BY
t.NAME, i.object_id, i.index_id, i.name
HAVING SUM(p.rows) = 0
from khtan # SQL Server Forums, this is used to drop all empty tables, maybe you could adapt it to output a count?
declare #name varchar(128), #sql nvarchar(2000), #i int
select #name = ''
while #name < (select max(name) from sysobjects where xtype = 'U')
begin
select #name = min(name) from sysobjects where xtype = 'U' and name > #name
select #sql = 'select #i = count(*) from [' + #name + ']'
exec sp_executesql #sql, N'#i int out', #i out
if #i = 0
begin
select #sql = 'drop table [' + #name + ']'
print #sql
-- unmask next to drop the table
-- exec (#sql)
end
end
I don't have SQLServer here but I could take a stab at it if you like.
