我用语句 adoquery.sql.add(‘update tab1 set aa='+edit1.Text+'')；更新aa字段(aa为number类型），edit1.txt= 102.32,但运行提示“ '102.32'is not a valid integer value',错误，请问应该怎么写sql语句？
decimal and numeric Numeric data types with fixed precision and scale.decimal[(p[, s])] and numeric[(p[, s])]Fixed precision and scale numbers. When maximum precision is used, valid values are from - 10^38 +1 through 10^38 - 1. The SQL-92 synonyms for decimal are dec and dec(p, s).p (precision)Specifies the maximum total number of decimal digits that can be stored, both to the left and to the right of the decimal point. The precision must be a value from 1 through the maximum precision. The maximum precision is 38.s (scale)Specifies the maximum number of decimal digits that can be stored to the right of the decimal point. Scale must be a value from 0 through p. The default scale is 0; therefore, 0 <= s <= p. Maximum storage sizes vary, based on the precision.
给你个简单的例子； create table tablename ( aa numeric(5,2) )insert into tablename values(1.11)select * from tablename

create table tablename
(
aa numeric(5,2)
)insert into tablename
values(1.11)select * from tablename
