SetString(const char *, const char *, size

Sets a column to a string value.

public virtual bool SetString(
     const char * cname,
    const char * value,
    size_t len
)

cname The name of the column.
value The string value. Passing NULL is equivalent to calling the SetNull method.
len Optional. The length of the string in bytes or the UL_NULL_TERMINATED_STRING constant if the string is null-terminated. The SQLE_INVALID_PARAMETER constant is set if the len value is set larger than 32K. For large strings, call the AppendStringChunk method instead.
