sql-server-2016

In my current application, i am performing an update by invoking T-SQL Update command. The problem is when the same record is locked by other users at that time. At .NET application, the application will wait until SQL Server timeout, then it will throw the SqlException timeout. Is it possible to perform a check first whether a particular record is locked by other process rather than catching the exception ? No, not really. The standard way is to use try/catch and handle SqlException Number 1205 (deadlock victim), and retry your query: try { // do stuff... } catch (SqlException sqlEx) { switch

I have some clients getting weird bills. I was able to isolate the core problem: SELECT 199.96 - (0.0 * FLOOR(CAST(1.0 AS DECIMAL(19, 4)) * CAST(199.96 AS DECIMAL(19, 4)))) -- 200 what the? SELECT 199.96 - (0.0 * FLOOR(1.0 * CAST(199.96 AS DECIMAL(19, 4)))) -- 199.96 SELECT 199.96 - (0.0 * FLOOR(CAST(1.0 AS DECIMAL(19, 4)) * 199.96)) -- 199.96 SELECT 199.96 - (CAST(0.0 AS DECIMAL(19, 4)) * FLOOR(CAST(1.0 AS DECIMAL(19, 4)) * CAST(199.96 AS DECIMAL(19, 4)))) -- 199.96 SELECT 199.96 - (CAST(0.0 AS DECIMAL(19, 4)) * FLOOR(1.0 * CAST(199.96 AS DECIMAL(19, 4)))) -- 199.96 SELECT 199.96 - (CAST(0.0

I have a column with the name of a person in the following format: "LAST NAME, FIRST NAME" Only Upper Cases Allowed Space after comma optional I would like to use a regular expression like: [A-Z]+,[ ]?[A-Z]+ but I do not know how to do this in T-SQL. In Oracle, I would use REGEXP_LIKE, is there something similar for SQL Server 2016? I need something like the following: UPDATE table SET is_correct_format = 'YES' WHERE REGEXP_LIKE(table.name,'[A-Z]+,[ ]?[A-Z]+'); First, case sensitivity depends on the collation of the DB, though with LIKE you can specify case comparisons. With that... here is

Tonight I had run into this issue where all my databases on our production server were in a Recovery Pending state after doing a Windows (server 2016) Update, an update to my Redgate SQL Backup software and restarting the server. Looking at the logs I found that all of the databases were not accessible with an "Access denied" error. So I figured it was something to do with the user under which the MSSQLSERVER service was running. So I explicitly set permissions to the data and log folders for that user and restarted SQL Server service and all is fine again. HOWEVER, this server has been

I need to get the last item in an array from a JSON format. I have this JSON. @json = N'{ "solution": "xxxxxxxxxxxxxxxxxxxxx", "options": [ { "choice_id": 205073, "choice": "aaaa" }, { "choice_id": 205074, "choice": "bbbb" }, { "choice_id": 205075, "choice": "cccc" }, { "choice_id": 205076, "choice": "dddd" } ], }' And I would like to get @json = N'{ "solution": "xxxxxxxxxxxxxxxxxxxxx", "options": { "choice_id": 205076, "choice": "dddd" } } How can I achieve that result? You can try this DECLARE @json NVARCHAR(MAX) = N'{ "solution": "xxxxxxxxxxxxxxxxxxxxx", "options": [ { "choice_id": 205073,

I am using the following script: DECLARE @dbName NVARCHAR(20) = 'ABC'; EXEC ( N' USE ' + @dbName + ' GO -- Create Schema CREATE SCHEMA meta GO -- Create Log Table CREATE TABLE meta.LogAudit( [EventDate] [datetime] NOT NULL DEFAULT (getdate()), [EventType] [nvarchar](64) NULL ) GO ' ); but it throws me the following error. Msg 111, Level 15, State 1, Line 5 'CREATE SCHEMA' must be the first statement in a query batch. Msg 102, Level 15, State 1, Line 22 Incorrect syntax near 'GO'. Why is that? -- Edit: This answer seems to be answering my question: dynamic sql error: 'CREATE TRIGGER' must be
