SELECT nextval('AWARD_ID')
I am getting nextval as not built in function name in MS SQL Server. Kindly give any alternative if there is any.
It seems you are looking for SELECT NEXT VALUE FOR award_id.
Do you mean something like IDENT_CURRENT():
select IDENT_CURRENT('FOO') + IDENT_INCR('FOO')

I am new to writing sql queries in presto and was looking for a function similar to 'starts_with'.
If a string starts with a given substring then the query needs to return that record.
In Postgresql, I am currently doing select * from tableA where name~'^Joh'. Whats the equivalent of this in Presto?
PostgreSQL and presto are RDBMS based on SQL. It is weird to see that you've learned a PostgreSQL proprietary add on (regular expressions) to the language before learning the standard SQL functions. In SQL you use LIKE for pattern matches:
select * from tableA where name like 'Joh%';
You can use Like in SQL. You can go through this link https://www.w3schools.com/sql/sql_like.asp. Using like you can search for a specified pattern.
In presto you can use regexp_like() which runs little faster than other like operators.For your case try below query which should provide you with expected functionality.
select regexp_like('John', '^John')
I am trying to convert an Oracle query to a SQL Server and facing an issue. Can you please help me ?
Oracle Query:
select ORA_HASH(SYS_GUID()) as SEGMENTID from my_Table
I am looking for a function which is equivalent to ORA_HASH() function in SQL Server. I was searching in google and found that HASHBYTES() function is the one which works as ORA_HASH in SQL Server. But when I tried to use, the return value of this is Hexa decimal and on the other hand, ORA_HASH is returning an integer.
Can you please help me in proving the equivalent function to ORA_HASH in SQL Server which works same as ORA_HASH ?
You shall try CHECKSUM which as per doc is intended for use in building hash indexes. https://learn.microsoft.com/en-us/sql/t-sql/functions/checksum-transact-sql
I'm trying to filter results from a Query i have created in Microsoft Query to pull data from a database into my Excel sheet. Specifically I'm trying to filter out based on the nth character of a string.
I can easily filter out the based on the first char:
SOPOrderReturnLine.ItemCode Like 'A25%'
But I have no idea how I could filter to show only entries where the 10th char = "A". I'm sure I have to use a Substring function, but it's not familiar to me and I'm struggling to get it to work.
Try to edit your sql query and enter the following statement:
select * from SOPOrderReturnLine where substring(SOPOrderReturnLine.ItemCode,10,1) = 'A';
The statement should work for a MySql database as well as for an Sql Server in the background; (I've tested it with an MySql database).
Hope this helps.
In MSQuery (Jet under the covers, I think), the function is Mid.
SELECT * FROM tblLocation WHERE (Mid(LocationName,2,1)='e')
to find a lower case 'e' in the second location.
I assume when you say MS Query, you are running a query against a DBMS (SQL Server or some other via ODBC).
The use of substr, substring or mid should work, depending on which DBMS. That said, unless you're using MS Access, I think most DBMSs will support the underscore character as "any single character." It might even work in Access, but I don't know for sure. Therefore, I think in addition to the suggestions you've gotten, this will also work in most cases:
SOPOrderReturnLine.ItemCode Like '_________A%'
If you want to use substring, don't hold me to these, but I think:
Oracle / DB2 / SQLite - substr
Microsoft SQL Server / Sybase / MySQL - substring
MS Access - mid
PostgreSQL -substr or substring
Using MS Office+VBA (or, sometimes, Visual Studio 2010) I am looking for a way to query Excel-Files using only SQL Query, similar to this way of querying a textfile:
SELECT * FROM [Text;DATABASE=L:\Testfiles].test1.csv
As a result I would expect something like:
SELECT * FROM [Excel File=L:\Testfiles\test2.xls].[sheet1$A1:B1000]
I am not looking for a way to query Excel-Files with SQL and a ADODB-connection string (as depicted on connectionstrings.com or here on so.com), since I want all information regarding the data source inside the actual SQL-Code, and not split up between SQL and the connection setup in VB/VBA.
Any hints would be greatly appreciated.
Regards
Martin
You can use FROM clause like this:
FROM [sheet1$A3:E22] IN 'C:\path\MyFile.xlsx' [Excel 12.0;HDR=YES;IMEX=0]
I'm new with LinqPad and I would like to run two simple SQL statements at the same time so I can see the values in two tables. If I run the following individually it works but now when I run them at the same time. I get an error "invalid character".
Select * From Table1; Select * From Table2;
I found this article that suggests this format but it's not working for me.
How to run multiple SQL queries?
BTW: I'm using the free version of LinqPad 5.00.08 at the moment.
I know this is old, but I found this in my search for the same problem. (Using a SQL Server Compact database.) The way I was able to get mine to work was to add GO after each query.
SELECT * FROM Table1;
GO
SELECT * FROM Table2;
GO
You need to use Dump function
Table1.Dump();
Table2.Dump();
