Update multiple columns and conditional updates with CASE statements The CASE statement can be used to conditionally update columns based on specific criteria. This allows for more granular control over which values are updated and under what circumstances, adding flexibility to SQL updates. For example...
Can row_number() work in UNION STATEMENTS ? Can someone explain just exactly why xp_cmdshell is such a massive risk?! Can SQL Profiler give you the Missing Index information? Can Symmetric keys be used in a view? Can table-valued parameter be null? Can the "print" command be told not...
SQLLEN c; rc = SQLRowCount(stmt, &c); if(SQL_SUCCEEDED(rc)) { count += c; // If we can't return separate counts, maybe we should return a sum of all counts? } } else { // NOTE: You can choose to only keep the first error, build a list of errors, etc. error = my_er...
As long as you are not issuing millions of inserts, this shouldn't impact your performance too much. Multiple sql statements in one command is certainly more elegant, but we'll have to wait until v. 5.xx.xx is stable. Finally, have you tried the MySQL .Net driver? I believe it has...
Example: Multiple Recordset Objects for Multiple SQL Statements in a Single Command Const DS = "MySqlServer" Const DB = "Northwind" Const DP = "SQLOLEDB" Dim objRs As New ADODB.Recordset Dim CommandText As String Dim ConnctionString As String CommandText = "SELECT OrderID, " & _ "ShipNam...
Now that you created your select queries, it's time to combine them. In this step, you create the union query by copying and pasting the SQL statements. On theCreatetab, in theQueriesgroup, clickQuery Design. On theDesigntab, in theQuerygroup, clickUnion. Access hides the query design...
QSQL architecture consists of three layers: Parsing Layer: Used for parsing, validation, optimization of SQL statements, splitting of mixed SQL and finally generating Query Plan; Computing Layer: For routing query plan to a specific execution plan, then interpreted to executable code for given stora...
I am trying to create IF statements that I can then add conditional formatting to colour code.This is what I has so far but I cannot figure the rest...
Imports System.Data.SqlClient Module Module1 Sub Main() Dim x As Integer = 1 If x = 1 Then Try Using con As New SqlConnection("TheConnectionstringToTheDataBase") con.Open() Using com As New SqlCommand("Whatever SQL String", con) com.ExecuteNonQuery() com.CommandText = "Whatever SQL ...
To see an example of calling a stored procedure that returns multiple result sets along with update values, see Handling complex statements. Note When you make the call to the getMoreResults method of the SQLServerStatement class, the previously returned result set is implicitly closed. See also ...
