Bill Graham commented on HIVE-679:
----------------------------------
SQuirrelSQL allows a connection to be established without support for
DatabaseMetaData, which is being handled separately as part of HIVE-576. That
allows work on this issue to occur in parallel, ignoring the DatabaseMetaData
support in SQuirrelSQL.
I've got this working in my dev env with unit tests and will submit a patch
soon. Below is the scope of what I've had to implement:
HiveStatement
- getWarnings(), clearWarnings()
- close(), isClosed()
- execute(), getResultSet()
- getUpdateCount()
- setMaxRows()
HiveConnection
- getWarnings(), clearWarnings()
- close(), isClosed()
HiveDatabaseMetaData
- getDatabaseProductName() : Hive, getDatabaseProductVersion() : 0
- getProcedures() : null
- supportsCatalogsInTableDefinitions() : false
- supportsSchemasInTableDefinitions() : false
- supportsMultipleResultSets() : false
- supportsStoredProcedures() : false
HiveDriver
- getPropertyInfo : returns HOST, PORT, DBNAME properties
HiveResultSet
- getWarnings(), clearWarnings()
- wasNull()
- initializing column names and types
- support for maxRows
- Constructor throws SQLException instead of calling System.exit(1) on error
HiveResultSetMetaData
- getColumnType(int column)
- getColumnTypeName(int column)
- getColumnDisplaySize(int column)
- isAutoIncrement(int column) : false
- isCurrency(int column) : false
- isNullable(int column) : false
- getPrecision(int column) : 0 or -1 for DOUBLE ??? What should double
precision be?
- getScale(int column) : 0 or -1 for DOUBLE ??? What should double scope be?
