Zend Framework convert NULL string to actual NULL value for MySql -

-

While importing data using a multi-row insert with any (execution) function, many Rows were added for some columns with string faucet. How can I convert those null string to MySQL null values ​​so that I can check the empty values ​​by using is_null () in php when displaying data.

How can I avoid this problem? I was using the quote () function for each piece of data; Was this problem using bidding on empty areas? I was importing a CSV file

Thanks

To insert an SQL NULL or any other expression, you You can use a Zend_Db_Expr object even if you use the quote () , then the ZF passes these objects through unquoted < / P> $ null = New Zend_Db_Expr ("NULL"); $ Table = New MyTable (); $ Table- & gt; Insert (123, "abc", $ null);

Note that except for both the quote and parameter of Zend_Db_Expr , you are responsible for protecting against SQL injection.

This is tangent to your question, but keep in mind that whether you are bulking a CSV file. This can be 20x more than using multi-line INSERT .

c# - TypeConverter in propertygrid only converts from string, not to -

-
When the property grid is reached, only the conversion mechanism (often called) is called "Foo!" Returns the property string in the grid when I click to edit I get an exception Type.oo. Object type can not be changed to type. (Not properly translated,) What is a clue from the convert format, why not? And the error indicates that it is trying to convert to a string, not from. I think that when I want to edit this object, it will have to be converted from foo to string, and when the editing ends. Public class FooTypeConverter: StringConverter {public override object ConvertFrom (ITypeDescriptorContext Reference, CultureInfo Culture, Object Value) {New Foo (string) value); } Convert the public override object (Type the ITE DiskText Contact Reference, CultureInfo Culture, Object Value, Type Type) {Return "Foo!"; } Public override bool CanConvertFrom (ITypeDescriptorContext reference, type source type) {back true; } Public Override Bull CanConvertTo (ITypeDescrip...
