Using TO_CHAR function in SQL Server

to_char sql server
sql server to_char number
to_char sql w3schools
sql server convert
'to_char' is not a recognized built-in function name.
sql server to_date
oracle to_char timestamp
to_char in mysql

I want to execute this query:

SELECT *
FROM Production
WHERE TO_CHAR(Time_Stamp, "DD/MM/YYYY") = current_date
AND TO_CHAR(Time_STAMP, "HH:MM:SS") BETWEEN "00:00:00" AND "07:00:00"

My Time_Stamp field looks like : "DD/MM/YYYY HH:MM:SS"

Unfortunately, function TO_CHAR doesn't exist in SQL Server.

How can I transform my query so it can work on SQL Server?

There is no TO_CHAR in SQL Server. If you need to pass a date use the ISO formats yyyyMMdd or yyyy-MM-ddThh:mm:ss.sssssss or for a time just hh:mm:ss.sssssss.

Seeing, however, that is seems you have values that are for today (I assume that is what current_date is), looks like you want this:

SELECT *
FROM Production
WHERE Time_Stamp >= DATEADD(DAY,DATEDIFF(DAY,0,GETDATE()),0)
  AND Time_Stamp < DATEADD(HOUR,7,DATEADD(DAY,DATEDIFF(DAY,0,GETDATE()),0));

How to write to TO_CHAR and TO_DATE SQL Server?, Use the Convert Function in SQL Server.i.e.. To Convert to a Character - Select Convert(Varchar(25), <Date>). To Convert to a Date - Select Convert(datetime� In Oracle, TO_CHAR function converts a datetime value (DATE, TIMESTAMP data types i.e.) to a string using the specified format. In SQL Server, you can use CONVERT or CAST functions to convert a datetime value (DATETIME, DATETIME2 data types i.e.) to a string.

you can use cast()

SELECT *
FROM Production
WHERE cast(Time_Stamp as date) = cast(getdate() as date)
AND cast(Time_STAMP as time(0)) BETWEEN "00:00:00" AND "07:00:00"

MS SQL Server equivalent of to_char, You can use format() in Sql Server 2012+: select format(getdate(),'MM/dd/yyyy hh :mm tt'). rextester demo: http://rextester.com/QWPWO57409. string functions ascii char charindex concat concat with + concat_ws datalength difference format left len lower ltrim nchar patindex quotename replace replicate reverse right rtrim soundex space str stuff substring translate trim unicode upper numeric functions abs acos asin atan atn2 avg ceiling count cos cot degrees exp floor log log10 max

An alternative method is:

SELECT *
FROM Production
WHERE Time_Stamp >= CONVERT(DATE, GETDATE()) AND
      Time_Stamp < DATEADD(HOUR, 1, CONVERT(datetime, CONVERT(DATE, GETDATE())));

With this formulation, an index on TIME_STAMP can be used for the comparison of both the data and the time.

Oracle / PLSQL: TO_CHAR Function, Oracle / PLSQL: TO_CHAR Function. Description. The Oracle/PLSQL TO_CHAR function converts a number or date to a string. Syntax. The syntax for the TO_CHAR function in Oracle/PLSQL is: TO_CHAR( value [, format_mask] [, nls_language] ) Returns. The TO_CHAR function returns a string value. Applies To. This SQL Server tutorial explains how to use the CHAR function in SQL Server (Transact-SQL) with syntax and examples. In SQL Server (Transact-SQL), the CHAR function is the opposite of the ASCII function. It returns the character based on the NUMBER code.

SQL Server CONVERT() Function, Well organized and easy to understand Web building tutorials with lots of examples of how to use HTML, CSS, JavaScript, SQL, PHP, Python,� The SQL Server CHAR String Function converts any of 256 the integer ASCII codes to a character value. It would be impossible to remember them all, so I put this document together to show the integer values along with their corresponding string values, plus some examples for an easy reference.

Using Conversion Functions, The TO_CHAR function is used to have Oracle 11g display dates in a particular format. Format models are case sensitive and must be enclosed within single quotes. Consider the below SELECT query. The query format the HIRE_DATE and SALARY columns of EMPLOYEES table using TO_CHAR function. Even though CAST() is a standard-SQL function, not so many database systems support it. Convert date to string using TO_CHAR() function. The DB2, Oracle, MySQL and PostgreSQL provide a function named TO_CHAR() that has a similar feature to the CAST function. You can use the TO_CHAR() function to format a date as a string.

TO_CHAR (datetime), Database SQL Reference TO_CHAR (datetime) converts a datetime or interval value of DATE , TIMESTAMP , TIMESTAMP WITH TIME ZONE , or If you omit ' nlsparam' , then this function uses the default date language for your session. I know how to use TO_CHAR function in TOAD but how to get same output if I use in SQL Server 2008. Is there any conversion function in SQL Server for TO_CHAR? Please help me in writing a query in SQL Server. Thanks in advance select * from emp where to_char(hiredate, 'yy') like '82'; Output

Comments
  • What is your expected output ?
  • Unrelated, but: using TO_CHAR(Time_Stamp, "DD/MM/YYYY") = current_date in Oracle (or Postgres) is a really bad idea to begin with. You are comparing a string to a DATE value
  • I want to sort all the data that had been add during the night.
  • I don't understand why you are using DATEADD() ?
  • As you want times between 7 and 8 @MissKnacki , so I'm added 7 hours to the current date.
  • I wanted to try this method but SQL server tell me that DATEDIFF function need 3 arguments...
  • Sorry, @MissKnacki, there was a typographical error. I've edited the answer.
  • Have a go yourself first, @MissKnacki . If you get styuck, as a new question, explaining why it didn't work. YOu should, however, simply be able to change the logic above.
  • Careful with those CASTs. cast(Time_STAMP as time(0)) isn't SARGable, so the indexes won't be used, and cast(Time_Stamp as date) is SARGable, but doesn't mean you should do it: Cast to date is sargable but is it a good idea?
  • This won't work. HOUR is not a compatible with the date data type as it has no time property; you'll get the error The datepart hour is not supported by date function dateadd for data type date. The smallest increment you can use with a date is DAY.
  • @Larnu . . . Thank you. I fixed the answer. Why doesn't SQL Server just do the conversion implicitly in this case?
  • I can only guess, but probably because it wouldn't know what data type to convert to, datetime or datetime2 (and if the latter, with what scale). As a result you need to be specific.
  • @Larnu . . . But it has behaved this way before datetime2 existed. The lack of conversion goes way back. What is ironic is that 0 is converted to a datetime.
  • date didn't exist before datetime2 existed, Gordon, so "But it has behaved this way before datetime2 existed" is simply untrue. Both date and datetime2 (along with time and datetimeoffset) were added in SQL Server 2008 (SQL Server 2008: The New Data Types). You have never been about to use any period less than a DAY with DATEADD and the date datatype.
