DbColumnInfo

Ecng.Data

Represents column metadata read from a live database.

Construtores

public DbColumnInfo(string TableName, string ColumnName, string DataType, bool IsNullable, int? MaxLength, int? NumericPrecision, int? NumericScale, bool IsComputed)

dbColumnInfo = DbColumnInfo(TableName, ColumnName, DataType, IsNullable, MaxLength, NumericPrecision, NumericScale, IsComputed)

Represents column metadata read from a live database.

TableName: The table name.
ColumnName: The column name.
DataType: SQL data type name (e.g. "nvarchar", "bigint").
IsNullable: Whether the column allows NULLs.
MaxLength: Max character length for string columns, or null.
NumericPrecision: Numeric precision, or the fractional-second digits of a date/time column; null when the column has neither.
NumericScale: Numeric scale, or null.
IsComputed: Whether the column is computed (calculated).
