Struct dpiShardingKeyColumn 

#[repr(C)]
pub struct dpiShardingKeyColumn {
    pub oracleTypeNum: dpiOracleTypeNum,
    pub nativeTypeNum: dpiNativeTypeNum,
    pub value: dpiDataBuffer,
}

This structure is used for passing sharding key column values to the database. It is part of the structure dpiConnCreateParams.

Fields

oracleTypeNum: dpiOracleTypeNum

Specifies the Oracle type of the column which makes up the sharding key. It is expected to be one of the values from the enumeration dpiOracleTypeNum but currently only the value DPI_ORACLE_TYPE_VARCHAR is supported.

nativeTypeNum: dpiNativeTypeNum

Specifies the native type of the column which makes up the sharding key. It is expected to be one of the values from the enumeration dpiNativeTypeNum but currently only the value DPI_NATIVE_TYPE_BYTES is supported.

value: dpiDataBuffer

Specifies the value of the column which makes up the sharding key. It is a union of type dpiDataBuffer and the member of the union that is set must correspond to the value of the member [dpiShardingKeyColumn.nativeTypeNum].
