- Abstracts ADO.NET batching to maintain the illusion that a single logical batch
- exists for the whole session, even when batching is disabled.
- Provides transparent
- This will be useful once ADO.NET gets support for batching. Until that point - no code exists that will do batching, but this will provide a good point to do - error checking and making sure the correct number of rows were affected. -

- concat(?1, ?2) to concatenate two strings
- p1 and p2. Target SQL function will be dialect-specific, e.g. (?1 || ?2) for
- Oracle, concat(?1, ?2) for MySql, (?1 + ?2) for MS SQL.
- Each dialect will define a template as a string (exactly like above) marking function
- parameters with '?' followed by parameter's index (first index is 1).
-
- This method assumes that the name is not already Quoted. So if the name passed
- in is
- If the aliasName is already enclosed in the OpenQuote and CloseQuote then this - method will return the aliasName that was passed in without going through any - Quoting process. So if aliasName is passed in already Quoted make sure that - you have escaped all of the chars according to your DataBase's specifications. -
-- If the columnName is already enclosed in the OpenQuote and CloseQuote then this - method will return the columnName that was passed in without going through any - Quoting process. So if columnName is passed in already Quoted make sure that - you have escaped all of the chars according to your DataBase's specifications. -
-- If the tableName is already enclosed in the OpenQuote and CloseQuote then this - method will return the tableName that was passed in without going through any - Quoting process. So if tableName is passed in already Quoted make sure that - you have escaped all of the chars according to your DataBase's specifications. -
-- If the schemaName is already enclosed in the OpenQuote and CloseQuote then this - method will return the schemaName that was passed in without going through any - Quoting process. So if schemaName is passed in already Quoted make sure that - you have escaped all of the chars according to your DataBase's specifications. -
-
- This method checks the string
- After the OpenQuote and CloseQuote have been cleaned from the string
- The following quoted values return these results - "quoted" = quoted - "quote""d" = quote"d - quote""d = quote"d -
-- If this implementation is not sufficient for your Dialect then it needs to be overridden. - MsSql2000Dialect is an example of where UnQuoting rules are different. -
-- Author: Ioan Bizau -
-- This dialect probably will not work with schema-export. If anyone out there - can fill in the ctor with DbTypes to Strings that would be helpful. -
- The dialect defaults the following configuration properties: -
- Names.Put(DbType, "TEXT" );
- Names.Put(DbType, 255, "VARCHAR($l)" );
- Names.Put(DbType, 65534, "LONGVARCHAR($l)" );
-
- will give you back the following:
-
- Names.Get(DbType) // --> "TEXT" (default)
- Names.Get(DbType,100) // --> "VARCHAR(100)" (100 is in [0:255])
- Names.Get(DbType,1000) // --> "LONGVARCHAR(1000)" (100 is in [256:65534])
- Names.Get(DbType,100000) // --> "TEXT" (default)
-
- On the other hand, simply putting
-
- Names.Put(DbType, "VARCHAR($l)" );
-
- would result in
-
- Names.Get(DbType) // --> "VARCHAR($l)" (will cause trouble)
- Names.Get(DbType,100) // --> "VARCHAR(100)"
- Names.Get(DbType,1000) // --> "VARCHAR(1000)"
- Names.Get(DbType,10000) // --> "VARCHAR(10000)"
