/*
Create information_schema table using schema_table data
@note
For MYSQL_TYPE_DECIMAL fields only, the field_length member has encoded
into it two numbers, based on modulus of base-10 numbers. In the ones
position is the number of decimals. Tens position is unused. In the
hundreds and thousands position is a two-digit decimal number representing
length. Encode this value with (decimals*100)+length , where
0<decimals<10 and 0<=length<100 .
