Public Member Methods | |
| constructor (AbstractDatasource nds, string nname, *hash opts) | |
| Creates the object from the arguments. | |
| 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< auto > | getColumnSqlNames (softlist< auto > cols) |
| returns a list of column names for use in SQL strings More... | |
| hash< auto > | getExpressionMap () |
| Returns the expression map for PostgreSQL. | |
| string | getSchemaName () |
| returns the schema name | |
| string | getSqlName () |
| returns the name of the table to be used in SQL (with a possible qualifiers for schema, etc) | |
| *string | getTablespaceName () |
| returns the data tablespace name for the table or NOTHING if none is known | |
| code | getUpsertClosure (hash< auto > row, int upsert_strategy=UpsertAuto, *hash< auto > opt) |
| returns a closure for performing upserts More... | |
| bool | hasArrayBind () |
| returns False because the pgsql driver does not support array binds / bulk DML operations | |
| bool | hasAtomicUpsert () |
| Returns True if the server supports atomic upsert/merge operations. | |

Private Member Methods | |
| clearImpl () | |
| clears PostgreSQL-specific table information | |
| 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 | |
| doSelectOrderByWithOffsetSqlUnlockedImpl (reference< hash< QueryInfo > > info, reference< string > sql, list< auto > coll) | |
| processes a string for use in SQL select statements when there is an "order by" and "offset" argument | |
| hash | getColumnOperatorMapImpl () |
| returns the column operator map for this object | |
| string | getCreateSqlImpl (list l) |
| returns a string that can be used to create the table in the database | |
| string | getCreateTableSqlImpl (*hash opt) |
| returns a string that can be used to create the table in the database | |
| hash | 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 | getRawUpdateOperatorMap () |
| returns the raw (default) update operator map for this object | |
| AbstractSavepointHelper | getSavepointHelperImpl (*string savepoint) |
| get DB-specific savepoint helper More... | |
| getServerVersion () | |
| Sets the internal PostgreSQL server version. | |
| *string | getSqlValueImpl (auto v) |
| returns a string for use in SQL queries representing the DB-specific value of the argument More... | |

| transient Mutex | pg_state () |
| Lock for atomicity for setting state info. | |
| bool | supportsTablespacesImpl () |
| returns True if the database support tablespaces | |
| auto | tryExecArgsImpl (string sql, *softlist< auto > args) |
| tries to execute a command so that if an error occurs the current transaction status is not lost | |
| auto | tryExecRawImpl (string sql, *softlist< auto > args) |
| tries to execute a command so that if an error occurs the current transaction status is not lost | |
| bool | uniqueIndexCreatesConstraintImpl () |
| returns True if the database automatically creates a unique constraint when a unique index is created (ex: mysql) | |

| list< auto > PgsqlSqlUtilBase::PgsqlTable::getColumnSqlNames | ( | softlist< auto > | 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
|

get DB-specific savepoint helper
| savepoint | the savepoint string, if not given a unique savepoint string will be generated |
Implements SqlUtil::AbstractTable.
|
privatevirtual |
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
Implements SqlUtil::AbstractTable.
| code PgsqlSqlUtilBase::PgsqlTable::getUpsertClosure | ( | hash< auto > | row, |
| int | upsert_strategy = UpsertAuto, |
||
| *hash< auto > | 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 atomic merge/update statement is returned if the server version is >= 9.5, for earlier versions upsert operations are not atomic
|
privatevirtual |
Returns True if the exception was raised because of a duplicate row / key error.
Implements SqlUtil::AbstractTable.
| const PgsqlSqlUtilBase::PgsqlTable::PgsqlTableDescriptionHashOptions = ... |
extends SqlUtil::AbstractTable::TableDescriptionHashOptions with "functions"
for table functions required by triggers on the table
