Question

I needed to insert an array field into a database and I was pleased to notice that PostGreSQL had that functionality. But now I am not able to insert the data using the tables active record.

I have tried the below calls with no success

$active_record->array_column = $_array_of_values;

which gives me the exception

Exception Raised:CDbCommand failed to execute the SQL statement: SQLSTATE[22P02]: Invalid text representation: 7 ERROR: array value must start with “{” or dimension information

I have also tried this using

foreach($_array_of_values as $value){
    $active_record->array_column[] = $value;
}

which tells me

Indirect modification of overloaded property FeatureRaw::$colors_names has no effect

Can anyone help me with this?
Thanks!

Answer 1

Data must be inserted in the form (text representation of an ARRAY):

INSERT INTO tbl (arr_col) VALUES ('{23,45}')

Or:

INSERT INTO tbl (arr_col) VALUES ('{foo,"bar, with comma"}')

So you need to enclose your array values in '{}' and separate them with comma ,. Use double quotes "" around text values that include a comma.

I listed more syntax variants to insert arrays in a related answer.
