represents an Oracle table More...
#include <OracleSqlUtil.qm.dox.h>
Public Member Methods | |
| bool | bindEmptyStringsAsNull () |
| returns True because Oracle treats empty strings like NULL on insert More... | |
| string | getBaseType () |
returns the base type of the underlying object (either "table" or "view") More... | |
| code | getBulkUpsertClosure (hash example_row, int upsert_strategy=AbstractTable::UpsertAuto, *hash opt) |
| Oracle always supports bulk merging. | |
| string | getColumnSqlName (string col) |
| returns the column name for use in SQL strings; subclasses can return a special string in case the column name is a reserved word | |
| list | getColumnSqlNames (softlist cols) |
| returns a list of column names for use in SQL strings; subclasses can process the argument list in case a column name is a reserved word | |
| *string | getComment () |
| returns any table comment or NOTHING if none is known | |
| hash< auto > | getExpressionMap () |
| Returns the expression map for Oracle. | |
| string | getSchemaName () |
| returns the schema name | |
| string | getSqlName () |
| returns the schema and table name in dot notation | |
| *string | getTablespaceName () |
| returns the data tablespace name for the table if any or NOTHING if none is known | |
| code | getUpsertClosure (hash< auto > row, int upsert_strategy=UpsertAuto, *hash opt) |
| returns a closure for performing upserts; if the upsert_strategy argument is UpsertInsertFirst or UpsertUpdateFirst, then this argument is ignored and a closure using an Oracle merge statement is returned | |
| hash< auto > | getWhereOperatorMap () |
| returns the "where" operator map for Oracle | |
| bool | hasArrayBind () |
| returns True because the oracle driver supports array binds / bulk DML operations | |
| bool | isView () |
| This method can change itself or disappear in the near future. Do not use it. | |

Private Member Methods | |
| bool | asteriskRequiresPrefix () |
returns True if the database requires a wildcard "*" to be prefixed with the table name when it appears with other column arguments in a select statement | |
| bool | constraintsLinkedToIndexesImpl () |
| returns True if the database links constraints to indexes (ie dropping the constraint drops the index, etc) | |
| copyImpl (AbstractTable old) | |
| db-specific copy actions | |
| doSelectLimitOnlyUnlockedImpl (reference< hash< QueryInfo > > info, reference< string > sql) | |
| processes a string for use in SQL select statements when there is a "limit" argument, but no "orderby" or "offset" arguments | |
| hash< auto > | getColumnOperatorMapImpl () |
| returns the column operator map for this object | |
| hash< auto > | getInsertOperatorMap () |
| returns the insert operator map for this object | |
| AbstractDataProviderType | getNumericTypeImpl (string native_type, bool nullable, *hash< auto > options) |
| returns the type for number / numeric columns for the database so that data conversions can be handled properly | |
| *hash< auto > | getPseudoColumnHash () |
| returns a hash of valid pseudocolumns | |
| hash< auto > | getRawUpdateOperatorMap () |
| returns the raw (default) update operator map for this object | |
| AbstractSavepointHelper | getSavepointHelperImpl (*string savepoint) |
| get DB-specific savepoint helper More... | |
| hash< auto > | getSelectOptions () |
| override in subclasses to return driver-specific options | |
| *string | getSqlValueImpl (auto v) |
| returns a string for use in SQL queries representing the DB-specific value of the argument; returns NOTHING if the type cannot be converted to an SQL string | |
| code | getUpsertInsertOnly (Columns cols, hash< auto > row, *hash opt) |
| high-performance "insert only" upsert supporting bulk DML | |
| code | getUpsertUpdateOnly (Columns cols, hash< auto > row, *hash opt) |
| high-performance "update only" upsert supporting bulk DML | |
| bool | isDuplicateRowErrorImpl (hash< ExceptionInfo > ex) |

Returns True if the current connection supports optimized limit option handling. More... | |
| bool | supportsTablespacesImpl () |
