Detailed Description

the Oracle specialization for SqlUtil::AbstractDatabase

Member Function Documentation

◆ getMaximumPrecision()

int OracleSqlUtil::OracleDatabase::getMaximumPrecision ( )

Returns the maximum precision for numeric or decimal columns.

Returns
-1 means, no maximum
Since
OracleSqlUtil 1.4.3

◆ rebuildIndexAnalyze() [1/2]

bool OracleSqlUtil::OracleDatabase::rebuildIndexAnalyze ( AbstractIndex  index,
int  maxh,
int  maxleaf 
)

analyze index with ALTER INDEX ANAYZE. Then it checks INDEX_STATS for advices to rebuild.

Outputs of this method are hints only. Real investigation of index is strongly recommended.

Warning
content of this method can be changed anytime when there will be any better way how to analyze indexes.
Parameters
indexan AbstractIndex to analyze
maxhmaximum oracle index height before rebuilding index
maxleafmaximum oracle percentage of deleted leaf nodes before rebuilding index
Returns
bool True for "suggested for rebuilding", False for "no action needed"
Exceptions
ANALYZE-INDEX-ERRORif there are no data in INDEX_STATS table

◆ rebuildIndexAnalyze() [2/2]

bool OracleSqlUtil::OracleDatabase::rebuildIndexAnalyze ( string  name,
int  maxh,
int  maxleaf 
)

analyze index with ALTER INDEX ANAYZE. Then it checks INDEX_STATS for advices to rebuild.

Outputs of this method are hints only. Real investigation of index is strongly recommended.

Warning
content of this method can be changed anytime when there will be any better way how to analyze indexes.
Parameters
nameindex name
maxhmaximum oracle index height before rebuilding index
maxleafmaximum oracle percentage of deleted leaf nodes before rebuilding index
Returns
bool True for "suggested for rebuilding", False for "no action needed"
Exceptions
ANALYZE-INDEX-ERRORif there are no data in INDEX_STATS table

oracle-specific schema description keys

This constant extends SqlUtil::AbstractDatabase::SchemaDescriptionOptions as returned by OracleSqlUtil::OracleDatabase::getSchemaDescriptionOptions with the following Oracle-specific keys:

  • types: for Oracle type definitions
  • type_map: to automatically renaming Oracle types during schema alignment
  • packages: for Oracle package descriptions
  • package_map: for automatically renaming Oracle types during schema alignment
  • materialized_views: for Oracle materialized view descriptions
  • materialized_view_map: for automatically renaming Oracle materialized views during schema alignment
