Types used in various SQL related units Schema type to retrieve TSchemaType describes which schema information to retrieve in the TCustomSQLQuery.SetSchemaInfo call. Depending on its value, the result set of the dataset will have different fields, describing the requested schema data. The result data will always have the same structure. TCustomSQLQuery.SetSchemaInfo Retrieving Schema Information No schema User Tables in database System tables in database Stored procedures in database Columns in a table Parameters for a stored procedure Indexes for a table Packages (for databases that support them) List of schemas in database(s) (for databases that support them) Sequences (for databases that support them) Type describing the kind of SQL statement TStatementType describes the kind of SQL statement that was entered in the SQL property of a TSQLQuery component. TSQLQuery The statement type could not be detected. The statement is a SQL SELECT statement The statement is a SQL INSERT statement The statement is a SQL UPDATE statement The statement is a SQL DELETE statement The statement is a SQL DDL (Data Definition Language) statement The statement is a SQL get segment statement The statement is a SQL put segment statement The statement executes a stored procedure The statement starts a transaction The statement commits a transaction The statement rolls back a transaction The statement selects data for update Type of database event TDBEventType describes the type of a database event message as generated by TSQLConnection through the OnLog event. event. TSQLConnection TSQLConnection.OnLog TDBLogNotifyEvent Custom event message SQL prepare message SQLExecute message Fetch data message Transaction Commit message Transaction rollback message Parameter name and value message Actual SQL as sent to engine message Set of database event types TDBEventTypes is a set of values, which is used to filter the set of event messages that should be sent. The TSQLConnection.LogEvents property determines which events a particular connection will send. TSQLConnection.LogEvents TDBLogNotifyEvent GlobalDBLogHook Type to describe quote characters. TQuoteChars is an array of characters that describes the used delimiters for string values. List of TSqlObjectIndentifier instances TSqlObjectIdentifierList is a list class holding a list of elements. It is used in the TSQLConnection.GetObjectNames to return the list of objects requested. SQL Identifier properties object TSQLObjectIdentifier is a class that represents an SQL identifier in a database. It has 2 parts: the schema name and the object name. Collection which the object belongs to Object name. Schema in which object is defined. Schema name SchemaName is the name of the schema in which the object is defined. This is only set if the database actually supports schemas, for other databases, it is empty. Name of the object in the database ObjectName is the name of the object in the database. If the database supports schemas, then it must be combined with the SchemaName property in order to create a unique name for the object. Add an identifier to the list

AddIdentifier adds an identifier to the list with schema name ASchemaName and object name AObjectName. It returns the new identifier object. Both arguments are optional, their default value is the empty string.

No checking on duplicate entries is performed.

A new TSQLObjectIdentifier object The value for the ObjectName property The value for the SchemaName property Indexed access to all identifiers in the list. Identifiers gives indexed access to all objects in the list. Valid indexes run from 0 to Count-1. It is the default property of the list class. Numerical index to the list Collections Various conversion and formatting routines Return the full name of the object FullName returns the name of the object, prepended with the schema name if there is one. Both parts are separated by a dot (.) character. The fully qualified name of the object
