This Node may be affected by Windows Regional Settings.

Properties

Connection

Type: Connection Input
See Example Connection Configurations below for configuration information.

ConnectionString
Type: String
A .NET connection string including the provider name.

ParameterPrefix
Type: String
The character that is used to denote a variable for the database.

AllowNamedParameters
Type: Boolean
Set to true if the SQL database supports named (rather than indexed parameters).

ObjectEncapsulator
Type: String
Characters used to escape an object that contains characters that would otherwise be illegal.

SelectSql
Type: String
A SELECT statement template that can be used to query the column definition of a table by returning 0 rows.

TableXml

Type: Xml Input
An XML representation of the data to be updated or inserted (see Remarks).

KeyFields

Type: String Input
A comma-separated list of fields that represent key fields for the update or insert operation. These values will be matched in the target table to determine whether the row already exists. The key fields listed in this property must be supplied in the TableXml property. It is not necessary to supply key fields if AllowUpdate is false.

AllowInsert

Type: Boolean Input
Indicates whether inserts are allowed into the target table.

AllowUpdate

Type: Boolean Input
Indicates whether updates are allowed into the target table (requires at least one field to be specified in KeyFields).

RowsAffected

Type: Int32 Output
Returns the number of rows affected by the insert/update operation.

Remarks

The XML supplied should contain the following paths root\tablename\columnname. The name of the root node is not important. The second tier should contain the table name and only a single table can be updated per call. The third tier should contain the column name.

Here's an example of a payload that will add or insert two rows into a table called inventory :

<root>
	<inventory>
		<code>123</code>
		<description>first inventory item</description>
	</inventory>
	<inventory>
		<code>456</code>
		<description>second inventory item</description>
	</inventory>
</root>

When AllowUpdate is true, the fields specified in KeyFields will be matched from TableXml to the target table. All KeyFields supplied must exist in both TableXml and the target table. Multiple key fields should be separated with commas. Note that the specified KeyFields do not have to be the database primary key fields but should indicate the key fields for purposes of the update operation.

For example, if an inventory table contains the fields id (int), code (varchar(50)), description (varchar(100)), the KeyFields property could be set to code if it was necessary to update based on this value rather than the internal integer id field.

Connection Configurations

Refer to Integrating with SQL Databases for additional information including connection strings and Connection properties.

Note that the underlying .NET object being used (OdbcCommand), does not support named parameters. Therefore, ParameterPrefix should always be ? and AllowNamedParameters should be False.
