CHARACTER_MAXIMUM_LENGTH: the maximum length in number of
characters of the column currently iterated upon. This is a Flow variable, and it returns a
numeric string for binary or character data types and NULL for other types.

CHARACTER_OCTET_LENGTH: the maximum length in bytes of
the column currently iterated upon. This is a Flow variable, and it returns a numeric string
for binary or character data types and NULL for other types.

NUMERIC_PRECISION: the data precision of the column
currently iterated upon. This is a Flow variable, and it returns a numeric string for
approximate numeric data, exact numeric data, integer data, or monetary data and NULL for
other data types.

NUMERIC_PRECISION_RADIX: the data precision radix of the
column currently iterated upon. This is a Flow variable, and it returns a numeric string for
approximate numeric data, exact numeric data, integer data, or monetary data and NULL for
other data types.

NUMERIC_SCALE: the scale in digits allowed in the column
currently iterated upon. This is a Flow variable, and it returns a numeric string for
approximate numeric data, exact numeric data, integer data, or monetary data and NULL for
other data types.

DATETIME_PRECISION: the datetime precision in fractional
seconds of the column currently iterated upon. This is a Flow variable, and it returns a
numeric string if the data type is datetime or smalldatetime; otherwise, it returns

Usage rule

This component is to be used along with MSSql components,
especially with tMSSqlConnection.

Dynamic settings

Click the [+] button to add a row in the table
and fill the Code field with a context
variable to choose your database connection dynamically from multiple
connections planned in your Job. This feature is useful when you need to
access database tables having the same data structure but in different
databases, especially when you are working in an environment where you
cannot change your Job settings, for example, when your Job has to be
deployed and executed independent of Talend Studio.

Once a dynamic parameter is defined, the Component List box in the Basic
settings view becomes unusable.

For examples on using dynamic parameters, see Reading data from databases through context-based dynamic connections and Reading data from different MySQL databases using dynamically loaded connection parameters. For more information on Dynamic
settings and context variables, see Talend Studio
User Guide.
