UPDATE Statements
To modify existing records, use UPDATE statements.
Update Syntax
The UPDATE statement takes as input a comma-separated list of columns and new column values as name-value pairs in the SET clause, as shown in the following example:
UPDATE <table_name> SET { <column_reference> = <expression> } [ , ... ] WHERE { Id = <expression> } [ { AND | OR } ... ]
<expression> ::=
| @ <parameter>
| ?
| <literal>
You can use the ExecuteNonQuery method to execute data manipulation commands and retrieve the rows affected, as shown in the following example:
C#
String connectionString = "[email protected];Password=test_1234;Domain=test.quickbase.com;ApplicationToken='bwkxrb5da2wn57bzfh9xn24';"; using (QuickBaseConnection connection = new QuickBaseConnection(connectionString)) { int rowsAffected; QuickBaseCommand cmd = new QuickBaseCommand("UPDATE [CData].[QuickBase].SampleTable_1 SET Column1='John' WHERE Id = @myId", connection); cmd.Parameters.Add(new QuickBaseParameter("myId","6")); rowsAffected = cmd.ExecuteNonQuery(); }
VB.NET
Dim connectionString As [String] = "[email protected];Password=test_1234;Domain=test.quickbase.com;ApplicationToken='bwkxrb5da2wn57bzfh9xn24';" Using connection As New QuickBaseConnection(connectionString) Dim rowsAffected As Integer Dim cmd As New QuickBaseCommand("UPDATE [CData].[QuickBase].SampleTable_1 SET Column1='John' WHERE Id = @myId", connection) cmd.Parameters.Add(New QuickBaseParameter("myId", "6")) rowsAffected = cmd.ExecuteNonQuery() End Using
