Properties

AdditionalColumns	Specifies the additional columns to be added to source data. Type: array of objects(AdditionalColumns) (or Expression with resultType array of objects). To assign an object to this property use FromObjectAsJson<T>(T, JsonSerializerOptions). To assign an already formatted json string to this property use FromString(String). Examples: BinaryData.FromObjectAsJson("foo"): Creates a payload of "foo". BinaryData.FromString("\"foo\""): Creates a payload of "foo". BinaryData.FromObjectAsJson(new { key = "value" }): Creates a payload of { "key": "value" }. BinaryData.FromString("{\"key\": \"value\"}"): Creates a payload of { "key": "value" }. (Inherited from TabularSource)
AdditionalProperties	Additional Properties To assign an object to the value of this property use FromObjectAsJson<T>(T, JsonSerializerOptions). To assign an already formatted json string to this property use FromString(String). Examples: BinaryData.FromObjectAsJson("foo"): Creates a payload of "foo". BinaryData.FromString("\"foo\""): Creates a payload of "foo". BinaryData.FromObjectAsJson(new { key = "value" }): Creates a payload of { "key": "value" }. BinaryData.FromString("{\"key\": \"value\"}"): Creates a payload of { "key": "value" }. (Inherited from CopyActivitySource)
DisableMetricsCollection	If true, disable data store metrics collection. Default is false. Type: boolean (or Expression with resultType boolean). (Inherited from CopyActivitySource)
IsolationLevel	Specifies the transaction locking behavior for the SQL source. Allowed values: ReadCommitted/ReadUncommitted/RepeatableRead/Serializable/Snapshot. The default value is ReadCommitted. Type: string (or Expression with resultType string).
MaxConcurrentConnections	The maximum concurrent connection count for the source data store. Type: integer (or Expression with resultType integer). (Inherited from CopyActivitySource)
PartitionOption	The partition mechanism that will be used for Sql read in parallel. Possible values include: "None", "PhysicalPartitionsOfTable", "DynamicRange". Type: string (or Expression with resultType string).
PartitionSettings	The settings that will be leveraged for Sql source partitioning.
ProduceAdditionalTypes	Which additional types to produce. To assign an object to this property use FromObjectAsJson<T>(T, JsonSerializerOptions). To assign an already formatted json string to this property use FromString(String). Examples: BinaryData.FromObjectAsJson("foo"): Creates a payload of "foo". BinaryData.FromString("\"foo\""): Creates a payload of "foo". BinaryData.FromObjectAsJson(new { key = "value" }): Creates a payload of { "key": "value" }. BinaryData.FromString("{\"key\": \"value\"}"): Creates a payload of { "key": "value" }.
QueryTimeout	Query timeout. Type: string (or Expression with resultType string), pattern: ((\d+).)?(\d\d):(60|([0-5][0-9])):(60|([0-5][0-9])). (Inherited from TabularSource)
SourceRetryCount	Source retry count. Type: integer (or Expression with resultType integer). (Inherited from CopyActivitySource)
SourceRetryWait	Source retry wait. Type: string (or Expression with resultType string), pattern: ((\d+).)?(\d\d):(60|([0-5][0-9])):(60|([0-5][0-9])). (Inherited from CopyActivitySource)
SqlReaderQuery	SQL reader query. Type: string (or Expression with resultType string).
SqlReaderStoredProcedureName	Name of the stored procedure for a SQL Database source. This cannot be used at the same time as SqlReaderQuery. Type: string (or Expression with resultType string).
StoredProcedureParameters	Value and type setting for stored procedure parameters. Example: "{Parameter1: {value: "1", type: "int"}}". To assign an object to this property use FromObjectAsJson<T>(T, JsonSerializerOptions). To assign an already formatted json string to this property use FromString(String). Examples: BinaryData.FromObjectAsJson("foo"): Creates a payload of "foo". BinaryData.FromString("\"foo\""): Creates a payload of "foo". BinaryData.FromObjectAsJson(new { key = "value" }): Creates a payload of { "key": "value" }. BinaryData.FromString("{\"key\": \"value\"}"): Creates a payload of { "key": "value" }.
