Parameters

command
Type: System.String
A command to execute that is specific to a data source.

commandType
Type: System.Int32
The command type for the indicated command, specifying how to interpret the contents of the command parameter.

parameters
Type: array<Microsoft.VisualStudio.Data.DataParameter[]
An array of DataParameter objects for the specified command type. While this is an input parameter, the provider is still able to set properties on individual out and return value parameters.

commandTimeout
Type: System.Int32
The length of time, in seconds, to block the client before canceling the execution and returning to the caller. . A value of 0 indicates infinite timeout; a value of -1 indicates a provider default.

Return Value

Type: System.Int32
Returns a DDEX provider specific integer status code.

Exceptions

Exception	Condition
ArgumentNullException	The command or asyncCommandEvents are null.
ArgumentException	The commandType specifies an invalid type.
ArgumentOutOfRangeException	The commandTimeout is less than -1.
NotSupportedException	The provider does not support this method.

Remarks

In most cases, the outcome of the call to this method will be an indication of the number of rows affected.

Out and return value parameters may still be set using this call. They are not considered part of results.

Hinweis

Other exceptions that occur indicate that the parameter derivation failed for a provider-specified reason.
