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	getSqlName ()
	returns the name of the table to be used in SQL (with a possible qualifiers for schema, etc)
bool	hasArrayBind ()
	returns False because the sqlite3 driver does not support array binds / bulk DML operations
bool	hasReturningImpl ()
	returns True if the current database driver supports the "returning" clause in insert statements, False if not

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

Detailed Description

provides the Sqlite3-specific implementation of the AbstractTable interface

Member Function Documentation

getColumnSqlName()

string Sqlite3SqlUtil::Sqlite3Table::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

Sqlite3/MariaDB etc require column names to be enclosed in backticks instead of double quotes

getSavepointHelperImpl()

AbstractSavepointHelper Sqlite3SqlUtil::Sqlite3Table::getSavepointHelperImpl ( *string  savepoint )

privatevirtual

get DB-specific savepoint helper

Parameters

savepoint

the savepoint string, if not given a unique savepoint string will be generated

Since

SqlUtil 1.6

Implements SqlUtil::AbstractTable.

getSqlValue()

static *string Sqlite3SqlUtil::Sqlite3Table::getSqlValue ( auto  v )

static

returns a string for use in SQL queries representing the DB-specific value of the argument

Example:

string str = table.getSqlValue(date);

Parameters

v	the value to convert to an SQL value

Returns

a string representing the value usable in SQL strings for the given database driver

Exceptions

VALUE-ERROR

the given value cannot be converted to an SQL string (missing rules for value)

isDuplicateRowErrorImpl()

bool Sqlite3SqlUtil::Sqlite3Table::isDuplicateRowErrorImpl ( hash< ExceptionInfo >  ex )

privatevirtual

Returns True if the exception was raised because of a duplicate row / key error.

Since

Sqlite3SqlUtil 1.4.2

Implements SqlUtil::AbstractTable.
