Method Detail

convertSqlTypeToJavaType

public static Object convertSqlTypeToJavaType(int columnSqlType,
                                              Object object)
                                       throws DatabricksSQLException

Converts a SQL object to the appropriate Java object based on the SQL type.

Parameters:

columnSqlType - The SQL type of the column, as defined in java.sql.Types

object - The object to be converted

Returns:

The converted Java object

Throws:

DatabricksSQLException - If there's an error during the conversion process

convertSqlTypeToSpecificJavaType

public static Object convertSqlTypeToSpecificJavaType(Class<?> javaType,
                                                      int columnSqlType,
                                                      Object obj)
                                               throws DatabricksSQLException

Converts an object to a specific Java type based on the provided SQL type and desired Java class.

Parameters:

javaType - The Class object representing the desired Java type

columnSqlType - The SQL type of the column, as defined in java.sql.Types

obj - The object to be converted

Returns:

The converted object of the specified Java type

Throws:

DatabricksSQLException - If there's an error during the conversion process

getConverterForSqlType

public static ObjectConverter getConverterForSqlType(int columnSqlType)

Retrieves the appropriate ObjectConverter for a given SQL type.

Parameters:

columnSqlType - The SQL type of the column, as defined in java.sql.Types

Returns:

An ObjectConverter suitable for the specified SQL type

getConverterForColumnType

public static ObjectConverter getConverterForColumnType(int columnSqlType,
                                                        String columnTypeName)

Retrieves the appropriate ObjectConverter for a given SQL type and column type name. This method provides metadata-aware converter selection, checking the actual column type name first for database-specific types before falling back to SQL type-based selection.

Parameters:

columnSqlType - The SQL type of the column, as defined in java.sql.Types

columnTypeName - The actual column type name from metadata (e.g., "GEOMETRY", "GEOGRAPHY")

Returns:

An ObjectConverter suitable for the specified column type

isConversionSupported

public static boolean isConversionSupported(int fromType,
                                            int toType)
