Method Detail

makeSYSSTATEMENTSrow
public ExecRow makeSYSSTATEMENTSrow(boolean compileMe, SPSDescriptor spsDescriptor) throws StandardException
Make a SYSSTATEMENTS row.WARNING: When empty row is true, this method takes a snapshot of the SPSD and creates a row. It is imperative that that row remain consistent with the descriptor (the valid and StorablePreparedStatement fields must be in sync). If this row is to be written out and valid is true, then this call and the insert should be synchronized on the SPSD. This method has NO synchronization.
- Parameters:
compileMe
- passed into SPSDescriptorImpl.getPreparedStatement(). if true, we (re)compile the stmtspsDescriptor
- In-memory tuple to be converted to a disk row.- Returns:
- Row suitable for inserting into SYSSTATEMENTS.
- Throws:
StandardException
- thrown on failure
-
buildDescriptor
public TupleDescriptor buildDescriptor(ExecRow row, TupleDescriptor parentTupleDescriptor, DataDictionary dd) throws StandardException
Make an Tuple Descriptor out of a SYSSTATEMENTS row- Specified by:
buildDescriptor
in classCatalogRowFactory
- Parameters:
row
- a SYSSTATEMENTS rowparentTupleDescriptor
- unuseddd
- dataDictionary- Returns:
- a descriptor equivalent to a SYSSTATEMENTS row
- Throws:
StandardException
- thrown on failure
-
makeEmptyRow
public ExecRow makeEmptyRow() throws StandardException
Description copied from class:CatalogRowFactory
Return an empty row for this conglomerate.- Overrides:
makeEmptyRow
in classCatalogRowFactory
- Throws:
StandardException
-
buildColumnList
public SystemColumn[] buildColumnList() throws StandardException
Builds a list of columns suitable for creating this Catalog. The last column, the serialized statement, is not added to the column list. This is done deliberately to make it a 'hidden' column -- one that is not visible to customers, but is visible to the system.- Specified by:
buildColumnList
in classCatalogRowFactory
- Returns:
- array of SystemColumn suitable for making this catalog.
- Throws:
StandardException
-
getCreateHeapProperties
public java.util.Properties getCreateHeapProperties()
Get the Properties associated with creating the heap.- Overrides:
getCreateHeapProperties
in classCatalogRowFactory
- Returns:
- The Properties associated with creating the heap.
