I have a sql server database which contains 7000 tables and every table ends with a date. I need to find out all the tables of a particular date.
I have the table names as follows:
HouseKeeping_Stage1_12_6_14,
HouseKeeping_Stage1_13_6_14,
HouseKeeping_Stage1_14_6_14,
HouseKeeping_Stage2_12_6_14,
HouseKeeping_Stage2_13_6_14
I want to find out all the records which are associated with the date 12_6_14.
Please let me know how to write the query.
Using SSMS Object Explorer, right-click on the Tables node and select Filter-->Filter Settings. The list will be filtered accordingly.
Alternatively, you can query the catalog or INFORMATION_SCHEMA views:
SELECT
OBJECT_SCHEMA_NAME(object_id) AS schema_name
, name
FROM sys.tables
WHERE name LIKE '%[_]13[_]6[_]14%';
SELECT
TABLE_SCHEMA
, TABLE_NAME
FROM INFORMATION_SCHEMA.TABLES
WHERE TABLE_NAME LIKE '%[_]13[_]6[_]14%';
This should do the trick:
SELECT * FROM information_schema.tables
where table_name like '%12_6_14%'

I have the following query which works perfectly when searching for tables that contain a specific field name that I am looking for in an Oracle database
however it does not work in Netezza (Data Mart) when using the Toad Data point tool. Can someone let me know if there is anything similar to the query below which would work in a Netezza Data Mart environment.
Select DISTINCT TABLE_NAME, COLUMN_NAME
FROM ALL_TAB_COLUMNS
WHERE COLUMN NAME LIKE '%EXANOKE_FIELD_NAME%'
Select DISTINCT TABLE_NAME, COLUMN_NAME
FROM COLUMNS
WHERE COLUMN_NAME LIKE '%EXANOKE_FIELD_NAME%';
I have a list of columns. I want to build a query to find if the columns exists in the ServicingDB database.
We can also use the filter for the tables starting with abcd (example).
Thanks in advance.
You can use the below query to find out the Specific column along with database name, table name etc.
select * from information_schema.columns where column_name = 'yourColumnName'
I could not find answer to this question, despite it being very basic. How do I know whats the data type of all columns in SQL Server management System?
Col1 Col2 Col3 and so on
I wish to know the datatypes of each column in say Table1 where Table1 is the name of my table .
There are couple of options to see the data types of columns of the desired table -
Option 1
sp_help <tableName> e.g. sp_help Table1
Option 2
SELECT *
FROM INFORMATION_SCHEMA.COLUMNS
WHERE TABLE_NAME = 'Table1'
Option 3
Expand the Tables
Expand the desired table
Expand the columns
There are many several way to do this, one of them is to use schema :
select *
from INFORMATION_SCHEMA.COLUMNS
where TABLE_NAME = 'Table1' or
COLUMN_Name = 'col1';
I want to retrieve column names from a table through a db link but I'm not able to do it...
Although this query is working
SELECT *
FROM myTableName#myDbLink;
the following one is not:
SELECT column_name
FROM all_tab_columns#myDbLink
WHERE table_name = 'myTableName'
What's the correct way of retrieving the column names?
CaSE mATterS.
In Oracle, table names are - by default - in UPPERCASE, so - try with
SELECT column_name
FROM all_tab_columns#myDbLink
WHERE table_name = 'MYTABLENAME'
I have a table that contains databases.
I use a sql job to fill this table.
one of the columns in the table looks like this:
database_name (column name*)
master
tempdb
model
database1
database2
testdatabase1
testdatabase2
Next step in the job is to delete the system databases, I use the following code for this:
delete from table_name
where column_name in ('master','tempdb','model','msdb')
Now what I want is, to also delete all databases that containt TEST in their name. I tried something like this, but its not working.
delete from table_name
where column_name in ('master','tempdb','model','msdb','%test%')
Also tried:
delete from table_name
where column_name in ('master','tempdb','model','msdb')
and like ('%test%')
Can anyone help me out?
delete from table_name
where column_name in ('master','tempdb','model','msdb')
or column_name like '%test%'
use the above query.
