QUESTION
I'm using github.com/denisenkom/go-mssqldb
library and driver but getting an error sql: expected 0 arguments, got 3 exit status 1
when inserting new row.
ANSWER
Answered 2021-Nov-27 at 11:01This issue might be related to driver name used in the connection string. I've tried the same query with yours, the record is created without any errors.
I believe that you are currently using mssql in connection string; sql.Open("mssql", conn) (This issue has already been discussed in https://github.com/denisenkom/go-mssqldb/issues/594#issuecomment-809922317)
If you try again by replacing "mssql" to "sqlserver", the problem should be solved.
QUESTION
I want to get a list of records from a SQL database using LIKE with % before and after the search term. I'm using the github.com/denisenkom/go-mssqldb package. My query is as follows currently:
row, err := DB.Query("SELECT * FROM Person WHERE Name LIKE %@p1%", nameToSearch)
This throws the error: Incorrect syntax near '@p1'.
I've tried other variations of the query including the following:
SELECT * FROM Person WHERE Name LIKE '%%' @p1 '%%'
SELECT * FROM Person WHERE Name LIKE '%%' || @p1 || '%%'
These fail as well.
Is the driver I'm using not able to support Like's with wildcards?

row, err := DB.Query("SELECT * FROM wsd.CUSMASFL WHERE CMNAME LIKE '%' + @p1 + '%'", nameToSearch)
QUESTION
I have a requester that manages my SQL queries against an Azure SQL database. The function responsible for transaction queries is as follows:
...ANSWER
Answered 2021-Apr-23 at 05:34After some investigation, I discovered that the database connection grows stale after a 30 minute window, and modifying the lifetime or idle time of the connection pool doesn't really do anything to fix that. So, what I did to alleviate this problem was to modify my getConn
function to ping the server beforehand so I could ensure that the connection is "fresh", for lack of a better term.
QUESTION
This is my Go code. I am using version 1.13 Once the code starts running, the memory consumption continuously increases, never decreasing. I dont think I am creating new variables. I am only reusing global variables for all the storage.
I read online that the GC in Go should kick in every 2 minutes...?
EDIT: I am monitoring the memory consumption of the program on the Windows Task Manager. And the Memory starts at ~5MB, when the program starts to run and increases 0.3~0.5 MB every minute.
...ANSWER
Answered 2020-Jun-30 at 11:33General concept in Go is whatever implements io.Closer
(that has a Close()
method), when you have such a value which you don't intend to use anymore, you should call its Close()
method which in general frees resources which otherwise may not be freed immediately or not at all (ever).
Your db.QueryContext()
call is sql.Conn.QueryContext()
which returns an *sql.Rows
value which has a Close()
method. Do call that. Currently you're not even storing the returned sql.Rows
.
