T-SQL :- How to Search String in all Stored Procedures across All User Defined Databases

There are many different ways to accomplish this tasks.

Download Link https://gallery.technet.microsoft.com/T-SQL-How-to-Search-String-a1704fc6

The below examples uses undocumented sp’s to loop through all the user defined database to search the SP’s using given string

CREATE TABLE  #ProcSearch  (databaseName VARCHAR(100),ROUTINE_CATALOG varchar(50),ProcName VARCHAR(128),RoutineType varchar(100),CreateDate date)


DECLARE @command varchar(1000) 
SELECT @command = 'IF ''?'' NOT IN(''master'', ''model'', ''msdb'', ''tempdb'') BEGIN USE ? 
INSERT INTO #ProcSearch
SELECT ''?'',ROUTINE_CATALOG, ROUTINE_NAME, ROUTINE_TYPE, CREATED FROM INFORMATION_SCHEMA.ROUTINES WHERE ROUTINE_DEFINITION LIKE ''%Index_Name%'' AND (ROUTINE_TYPE=''PROCEDURE'' or ROUTINE_TYPE=''FUNCTION''); 
END' 
EXEC sp_MSforeachdb @command

SELECT * FROM #ProcSearch

DROP TABLE #ProcSearch

The below SQL uses SearchString as a parameter also it uses syscomments system view

CREATE TABLE #ProcSearch ([databaseNAme] Varchar(100),ProcName VARCHAR(128))

DECLARE @command varchar(1000) 
Declare @SearchString varchar(100)='Index_Name'
SELECT @command = 'IF ''?'' NOT IN(''master'', ''model'', ''msdb'', ''tempdb'') BEGIN USE ? 
INSERT INTO #ProcSearch ([databaseNAme],[ProcName])
SELECT ''?'', OBJECT_NAME(id) as ROUTINE_CATALOG FROM syscomments WHERE [text] LIKE ''%'+@SearchString+'%'' AND OBJECTPROPERTY(id, ''IsProcedure'') = 1 GROUP BY OBJECT_NAME(id)
END' 
EXEC sp_MSforeachdb @command

SELECT * FROM #ProcSearch

T-SQL – Read CSV files using OpenRowSet

We can directly access a CSV file using T-SQL.

Input file

Configure server to run Ad Hoc Distributed Queries

sp_configure 'Ad Hoc Distributed Queries',1

Check for Microsoft Access Driver on your system

SQL

select

T-SQL – Find Number of Rows of Database(s) tables Using Undocumented Procedure – sp_MSforeachdb and sp_MSforeachtable

On Technet forum, Op was looking for a way to get table cardinality for all databases in an instance.  There are many ways to get the result. This post gives you an idea and SQL in which undocumented SP’s being called  “sp_MSforeachdb and sp_MSforeachtable”.

The above undocumented SP’s  iterate through each database and each table of a SQL instance

Download SQL :- UndocumentSPToGetNoOfRowsAllDatabases

SQL:-

CREATE TABLE  #TableRowCounts  ([databaseNAme] Varchar(100),[TableName] VARCHAR(128), [RowCount] INT) ;

EXEC sp_MSforeachdb
@command1 = 'IF not exists(select 1 where ''?'' in (''master'',''model'',''msdb'',''tempdb''))
INSERT INTO #TableRowCounts ([databaseNAme],[TableName], [RowCount])
EXEC [?].dbo.sp_MSforeachtable @command1 = ''SELECT ''''?'''',''''&'''',count(1) FROM &'',@replacechar = ''&'''

SELECT * FROM #TableRowCounts
					
DROP TABLE #TableRowCounts	

Note:-The above query is expensive. Please use at your risk

Output-

The use of IF and Like clause with sp_MSforeachtable

EXEC [sp_MSforeachtable] @command1=N'
IF (N''?'' =''[dbo].[log]'')
BEGIN
 PRINT N''?''
 SELECT COUNT(*) from ? 
END'

EXEC [sp_MSforeachtable] @command1=N'
IF (N''?'' LIKE N''%Resource%]'')
BEGIN
 PRINT N''?''
 SELECT ''?'' TABLENAME,COUNT(*) CNT from ? 
END
'

The use of @whereand parameter to filter any object with sp_MSforeachtable

EXEC sp_msforeachtable
 @command1 ='SELECT ''?'',count(*) FROM ?'
,@whereand = ' And Object_id In (Select Object_id From sys.objects
Where name like ''%EMPLOYEE%'')'

OR

EXEC [sp_MSforeachtable]@command1=N'
 PRINT N''?''
 SELECT ''?'',COUNT(*) FROM ?',
 @whereand = N'AND o.[name] LIKE N''%EMPLOYEE%'''

SQL- Querying XML attributes from XML Column

Read XML column attributes in to two columns DimType and Dimvalue  from the below example also retrieve the data matching values[DimTypes (WIDTH or Height)].

‘<dimensions>

<dimension name=”width”  value=”12.77″/>

<dimension name=”height”  value=”0.14″/>

<dimension name=”depth”      value=”12.92″/>

</dimenstions>’

Download SQL :-  https://gallery.technet.microsoft.com/SQL-Querying-XML-f700bbb0

 SQL:-

DECLARE @xml XML
SELECT @xml = 
'<dimensions>
  <dimension name="height" value="0.14" /> 
  <dimension name="width"  value="12.77"/> 
</dimensions>'

SELECT  x.v.value('@name[1]', 'VARCHAR(100)') AS dimtype ,
        x.v.value('@value[1]', 'VARCHAR(100)') AS dimvalue
FROM    @xml.nodes('/dimensions/dimension') x(v)

create table #demo (field1 xml)
insert into #demo (field1) 
values ('<dimensions>
  <dimension name="height" value="0.14" /> 
  <dimension name="width"  value="12.77"/> 
</dimensions>')

SELECT  x.v.value('@name[1]', 'VARCHAR(100)') AS dimtype ,
        x.v.value('@value[1]', 'VARCHAR(100)') AS dimvalue
from #demo
cross apply field1.nodes('/dimensions/dimension') x(v)

Select data for DimType “height and Width”

DECLARE @xml XML
SELECT @xml = 
'<dimensions>
  <dimension name="height" value="0.14" /> 
  <dimension name="width"  value="12.77"/>

        x.v.value('@value[1]', 'VARCHAR(100)') AS dimvalue
FROM    @xml.nodes('/dimensions/dimension[@name = "height" or @name = "width"]') x(v)

Using Temp table and Join –

create table #demo (field1 xml)
insert into #demo (field1) 
values ('<dimensions>
 <dimension name="height" value="0.14" /> 
 <dimension name="width" value="12.77"/>

SELECT x.v.value('@name[1]', 'VARCHAR(100)') AS dimtype ,
 x.v.value('@value[1]', 'VARCHAR(100)') AS dimvalue
from #demo
cross apply field1.nodes('/dimensions/dimension[@name = "height" or @name = "width"]') x(v)

Using SQL Where Clause to fetch dimension type data ‘HEIGHT’ or ‘WIDTH’

CREATE TABLE #demo (field1 xml)
INSERT INTO #demo (field1) 
values ('<dimensions>
  <dimension name="height" value="0.14" /> 
  <dimension name="width"  value="12.77"/> 
  <dimension name="depth"   value="12.92"/>
</dimensions>')

select * from #demo

select 
dimtype,
dimvalue

(
SELECT  x.v.value('@name[1]', 'VARCHAR(100)') AS dimtype ,
        x.v.value('@value[1]', 'VARCHAR(100)') AS dimvalue
from #demo
cross apply field1.nodes('/dimensions/dimension') x(v)

T-SQL to Display Weekends Between two Dates

Different ways to find the weekend between two given dates. The SQL requires @begindate and @endate paramteters to be entered in the below SQL

Download T-SQL WeekendBetweenTwoValidDates

DECLARE @beginDate Date='20150101',
		@endDate Date='20150131'


DECLARE @Calendar Table
(CalendarDate Date Primary key, IsWeekend Bit)

WHILE @beginDate <= @endDate
BEGIN
INSERT INTO @Calendar
SELECT
@beginDate As CalendarDate
,(Case When DATEPART(Weekday, @beginDate) In (7, 1) Then 1 Else 0 End) As IsWeekend
Set @beginDate = DateAdd(Day, 1, @beginDate)
End

SELECT CalendarDate From @Calendar Where IsWeekend = 1

On SQL 2012 or higher version you can use choose function.

DECLARE @beginDate Date='20150101',
 @EndDate Date='20150131'


Declare @Calendar Table

'Weekday','Weekday','Weekday','Weekday','WEEKEND') 
Set @beginDate = DateAdd(Day, 1, @beginDate) 
End

Select CalendarDate From @Calendar where IsWeekend='WEEKEND'

Using Number table

There are many methods to find next business day. One common way is to use of calendar table.  This post is to get an output using T-SQL Or UDF function.

Download T-SQL  NextBusinessDay

The details are given below

The script can be executed by feeding Input values to SQL. In the below example @dt parameter accepts input value.

DECLARE @dt datetime='20150113'
SELECT DATEADD(dd,CASE WHEN DATEDIFF(dd,0,@dt)%7 > 3 THEN 7-DATEDIFF(dd,0,@dt)%7 ELSE 1 END,@dt)

The following methods the input is fed from Table.

Method 1: T-SQL

Declare @TestDate Table(MyDate date);
Insert @TestDate(MyDate) Values('20150112'), ('20150113'), ('20150114'), ('20150115'), ('20150116'), ('20150117'), ('20150118');

Select MyDate, DateAdd(day, Case DateDiff(day, '19000101', MyDate) % 7 When 4 Then 3 When 5 Then 2 Else 1 End, MyDate) As NextWeekDay
From @TestDate;

Method 2: T-SQL

Declare @TestDate Table(MyDate date);
Insert @TestDate(MyDate) Values('20150112'), ('20150113'), ('20150114'), ('20150115'), ('20150116'), ('20150117'), ('20150118');

SELECT MyDate,DATEADD(dd,CASE WHEN DATEDIFF(dd,0,MyDate)%7 > 3 THEN 7-DATEDIFF(dd,0,MyDate)%7 ELSE 1 END,MyDate) from @TestDate

Method 3 : UDF

CREATE FUNCTION dbo.UF_GetWorkingDay(@givenDate DATETIME)
RETURNS DATETIME
AS
BEGIN
 DECLARE @workingDate DATETIME
 IF (DATENAME(dw , @givenDate) = 'Friday')
 BEGIN
 SET @workingDate = DATEADD(day, 3, @givenDate)
 END
 ELSE IF (DATENAME(dw , @givenDate) = 'Saturday')
 BEGIN
 SET @workingDate = DATEADD(day, 2, @givenDate)
 END
 ELSE 
 BEGIN
 SET @workingDate = DATEADD(day, 1, @givenDate)
 END
 RETURN @workingDate
END

Declare @TestDate Table(MyDate date);
Insert @TestDate(MyDate) Values('20150112'), ('20150113'), ('20150114'), ('20150115'), ('20150116'), ('20150117'), ('20150118');
select MyDate,dbo.UF_GetWorkingDay(Mydate) from @TestDate
