Detailed Description

Class encapsulating a complete SQL table column with type and name.

In case of double (integer) type, a complete row may be returned as MATLAB matrix (vector). If any (row) element is non scalar, or an integer has no acceptable precise double representation, only a MATALB struct or cell variable can be returned. ValueSQL holds the double type up until its not tenable any more. Then all rows are stored with its individual value types.

Constructor & Destructor Documentation

~ValueSQLCol()

ValueSQLCol::~ValueSQLCol ( )

inline

Dtor.

Elements taking memory space will be freed.

Definition at line 1068 of file value.hpp.

Member Function Documentation

Destroy()

void ValueSQLCol::Destroy ( int  row )

inline

Deleting a single row element.

Parameters

[in]

row

Row number (0 based)

Definition at line 1081 of file value.hpp.

operator[]()

const ValueSQL ValueSQLCol::operator[] ( int  index )

inline

Indexing operator.

Parameters

[in]

index

Row number (0 based)

Returns

Always returns a copy of the original (no reference!)

Definition at line 1101 of file value.hpp.

swapToAnyType()

void ValueSQLCol::swapToAnyType ( )

inline

Transform storage type.

Switches from pure double representation to individual value types. Each former double element will be converted to ValueSQL type.
