IDbSpecificCreator Methods

The IDbSpecificCreator type exposes the following members.

Methods
  NameDescription
Public methodClampNameToLengthLimit
Method which clamps the passed in string to F__hashcode of toClamp if the length of toClamp is too long and this creator's useRestrictedLengthOnAliasesOfFields is set to true in the ctor (which is the case in DB2 and Oracle)
Public methodConvertComparisonOperator
Converts the passed in comparison operator to a string usable in a query.
Public methodConvertExpressionOperator
Converts the passed in expression operator (exop) to a string usable in a query
Public methodConvertExpressionToQueryFragment
Converts the expression to a query fragment and adds the parameters created during this process to the passed in parametercollection
Public methodConvertParameterOutputValueToRealValueT
Converts the parameter output value (contained in the parameter specified) to a real value. This is necessary for example if the value of the parameter is a value of a type native to an ADO.NET provider, like OracleDecimal.
Public methodConvertSetOperator
Converts the passed in set operator to a string usable in a query
Public methodConvertSortOperator
Converts the passed in sort operator to a string usable in a query
Public methodCreateCommand
Creates a new command instance
Public methodCreateCommand(DbConnection)
Creates a new command instance
Public methodCreateFieldName(IEntityFieldCore, IFieldPersistenceInfo, String, String, Boolean)
Creates the name for the field, and takes into account an aggregate function present and an expression present. If one or both are present, the field is replaced with (expression) or surrounded with (aggregate) the function (if applyAggregateFunction is true).
Public methodCreateFieldName(IFieldPersistenceInfo, String, String, String, String)
Creates a valid field name based on the passed in IFieldPersistenceInfo implementation. The fieldname is ready to use in queries and contains all pre/postfix characters required. This field name is not padded with an alias if that alias should be created. Effectively, this is the same as CreateFieldName(field persistence info, fieldname, false);
Public methodCreateFieldName(IFieldPersistenceInfo, String, String, Boolean, String, String)
Creats a valid field name based on the passed in IFieldPersistenceInfo implementation. The fieldname is ready to use in queries and contains all pre/postfix characters required.
Public methodCreateFieldNameSimple(IFieldPersistenceInfo, String)
Creates a valid field name based on the passed in IFieldPersistenceInfo implementation. The fieldname is ready to use in queries and contains all pre/postfix characters required. This field name is not padded with an alias if that alias should be created. Effectively, this is the same as CreateFieldNameSimple(field persistence info, fieldname, false);. The fieldname is 'simple' in that it doesn't contain any catalog, schema or table references.
Public methodCreateFieldNameSimple(IFieldPersistenceInfo, String, Boolean)
Creats a valid field name based on the passed in IFieldPersistenceInfo implementation. The fieldname is ready to use in queries and contains all pre/postfix characters required. The fieldname is 'simple' in that it doesn't contain any catalog, schema or table references.
Public methodCreateLikeParameter
Creates a valid Parameter for the pattern in a LIKE statement. This is a special case, because it shouldn't rely on the type of the field the LIKE statement is used with but should be the unicode varchar type.
Public methodCreateObjectName(IFieldPersistenceInfo)
Creates a valid object name (e.g. a name for a table or view) based on the passed in IFieldPersistenceInfo implementation. The fieldname is ready to use in queries and contains all pre/postfix characters required.
Public methodCreateObjectName(String, String, String)
Creates a valid object name (e.g. a name for a table or view) based on the fragments specified. The name is ready to use and contains all alias wrappings required.
Public methodCreateParameter(ParameterDirection, Object)
Creates a parameter based on the direction passed in and the value passed in.
Public methodCreateParameter(IEntityFieldCore, IFieldPersistenceInfo, ParameterDirection)
Creates a valid Parameter based on the passed in IEntityFieldCore implementation and the passed in IFieldPersistenceInfo instance
Public methodCreateParameter(IEntityFieldCore, IFieldPersistenceInfo, ParameterDirection, Object)
Creates a valid Parameter based on the passed in IEntityFieldCore implementation and the passed in IFieldPersistenceInfo instance
Public methodCreateParameter(String, Int32, ParameterDirection, Boolean, Byte, Byte, Object)
Creates a new, filled parameter.
Public methodCreateSubQuery(IEntityFieldCore, IFieldPersistenceInfo, IPredicate, Int64, ISortExpression, IRelationCollection, IGroupByCollection)
Creates a new Select Query which is ready to use as a subquery, based on the specified select list and the specified set of relations.
Public methodCreateSubQuery(IEntityFieldCore, IFieldPersistenceInfo, IPredicate, Int64, ISortExpression, IRelationCollection, IGroupByCollection, Boolean)
Creates a new Select Query which is ready to use as a subquery, based on the specified select list and the specified set of relations.
Public methodCreateTvfCallQuery
Creates a retrieval query from the tvfcall specified. The query will be a 'SELECT ... FROM functioncall' query.
Public methodCreateValidAlias
Routine which creates a valid alias string for the raw alias passed in. For example, the alias will be surrounded by "[]" on sqlserver. Used by the RelationCollection to produce a valid alias for joins.
Public methodDetermineDbTypeNameForValue
Determines the db type name (ADO.NET provider specific typename) for value.
Public methodFindRealAlias(String, String, String)
Finds the real alias for the entity + objectalias combination. A real alias is necessary as an entity mapped onto multiple tables (through inheritance) is aliased with a single object alias but each target has to have a different real alias. Checks all scopes.
Public methodFindRealAlias(String, String, String, Boolean)
Finds the real alias for the entity + objectalias combination. A real alias is necessary as an entity mapped onto multiple tables (through inheritance) is aliased with a single object alias but each target has to have a different real alias.
Public methodGetNewPerCallCatalogName
Gets the new catalog name from the per-call hashtable name overwrites set into this object. If no per call name pairs are defined or the name passed in isn't found, the same name passed in is returned
Public methodGetNewPerCallSchemaName
Gets the new schema name from the per-call hashtable name overwrites set into this object. If no per call name pairs are defined or the name passed in isn't found, the same name passed in is returned
Public methodStripObjectNameChars
Strips the object name chars from the name passed in. For example [name] will become name
Public methodToUpperFunctionName
Returns the SQL functionname to make a string uppercase.
