Indices can be changed / added / removed by a DBA without impact to the application (part of DB tuning), so it’s best not to assume their naming in an application deployment script. This can be useful to remove / replace certain indices without relying on index name.Victor Zakharovsqltsql/posts/2012-08-16-mssql-count-db-tables/Thu, 16 Aug 2012 00:00:00 +0000neolisk@gmail.com (Victor Zakharov)Sat, 05 Jun 2021 11:36:56 -0400/posts/2012-08-16-mssql-count-db-tables/Here is a one-liner: 1 SELECT COUNT(*) FROM (SELECT DISTINCT table_name FROM INFORMATION_SCHEMA.TABLES) aVictor Zakharovsql/posts/2012-02-29-cannot-open-sql-file-vs-2010/Wed, 29 Feb 2012 00:00:00 +0000neolisk@gmail.com (Victor Zakharov)Sat, 29 Feb 2020 15:34:59 -0500/posts/2012-02-29-cannot-open-sql-file-vs-2010/Environment hangs, completely at times, or just for several seconds. If it resumes after hanging, you are able to close the tab where this .SQL file would show up. In any case, you cannot see or edit anything in there, seeing this Visual Studio 2010 branded blue background all over the contents area. The solution, which worked for me - get the DVD with Visual Studio installation files and install from WCU\DAC\DACProjectSystemSetup_enu.Victor Zakharovdevopssql/posts/2011-10-11-sql-2008-error-log-growing-rapidly/Tue, 11 Oct 2011 00:00:00 +0000neolisk@gmail.com (Victor Zakharov)Sun, 01 Mar 2020 15:41:11 -0500/posts/2011-10-11-sql-2008-error-log-growing-rapidly/MS SQL server 2008 R2 was spamming the error log with the following two messages (got around 50GB of them in 4 days): Message A.

Need to change table_name and list of columns, as applicable. Statements will be generated only if required. To make things clear: If column does not exist within specified table, no drop will be generated. If column does not have a default constraint, no drop for this constraint will be generated.Victor Zakharovdevopssoftwaresql/posts/2011-02-17-oracle-alter-sequence-start-with-not-working/Thu, 17 Feb 2011 00:00:00 +0000neolisk@gmail.com (Victor Zakharov)Sun, 29 Mar 2020 19:23:55 -0400/posts/2011-02-17-oracle-alter-sequence-start-with-not-working/I googled over many websites explaining the error code and suggesting you do not change it. What if you really need to? One approach is to call NEXTVAL as many times to shift the sequence, so that it starts with your START WITH number (<SW>). A better one is to change INCREMENT BY to a certain value instead, then do NEXTVAL and revert INCREMENT BY. For example, suppose you currently have an increment = <I>, your current sequence value is <C>.Victor Zakharovoraclesql/posts/2010-03-12-sql-reporting-services-fix-border-thickness/Fri, 12 Mar 2010 00:00:00 +0000neolisk@gmail.com (Victor Zakharov)Mon, 12 Oct 2020 11:15:23 -0400/posts/2010-03-12-sql-reporting-services-fix-border-thickness/When the report is rendered on the screen in preview mode, it looks okay. However, when it is saved to PDF and/or printed, table borders might have slightly different thickness depending on relative location on the sheet. I believe this issue is related to DPI scaling. Anyway, there is a solution. At least, if you are not after any fancy behavior. To create solid border of the same thickness: Assign BorderStyle to Solid.Victor Zakharovsql
