ODPI-C Structure dpiDataTypeInfo

This structure is used for passing data type information from ODPI-C. It is part of the structures dpiObjectAttrInfo, dpiObjectTypeInfo and dpiQueryInfo.

dpiOracleTypeNum dpiDataTypeInfo.oracleTypeNum

Specifies the type of the data. It will be one of the values from the enumeration dpiOracleTypeNum, or 0 if the type is not supported by ODPI-C.

dpiNativeTypeNum dpiDataTypeInfo.defaultNativeTypeNum

Specifies the default native type for the data. It will be one of the values from the enumeration dpiNativeTypeNum, or 0 if the type is not supported by ODPI-C.

uint16_t dpiDataTypeInfo.ociTypeCode

Specifies the OCI type code for the data, which can be useful if the type is not supported by ODPI-C.

uint32_t dpiDataTypeInfo.dbSizeInBytes

Specifies the size in bytes (from the database’s perspective) of the data. This value is only populated for strings and binary data. For all other data the value is zero.

uint32_t dpiDataTypeInfo.clientSizeInBytes

Specifies the size in bytes (from the client’s perspective) of the data. This value is only populated for strings and binary data. For all other data the value is zero.

uint32_t dpiDataTypeInfo.sizeInChars

Specifies the size in characters of the data. This value is only populated for string data. For all other data the value is zero.

int16_t dpiDataTypeInfo.precision

Specifies the precision of the data. This value is only populated for numeric and interval data. For all other data the value is zero.

int8_t dpiDataTypeInfo.scale

Specifies the scale of the data. This value is only populated for numeric data. For all other data the value is zero.

int16_t dpiDataTypeInfo.fsPrecision

Specifies the fractional seconds precision of the data. This value is only populated for timestamp and interval day to second data. For all other data the value is zero.

dpiObjectType *dpiDataTypeInfo.objectType

Specifies a reference to the type of the object. This value is only populated for named type data. For all other data the value is NULL. This reference is owned by the object attribute, object type or statement and a call to dpiObjectType_addRef() must be made if the reference is going to be used beyond the lifetime of the owning object.
