Dear Prof. Ripley et al.,
I have a data frame with some variable names that contain the underscore
character ('_'). It seems that RODBC is not converting them to a
suitable
variable name for MySQL.
> sqlSave(channel, zz, addPK = TRUE, verbose = TRUE)
Query: CREATE TABLE zz (rownames varchar(255) PRIMARY KEY, NAME
varchar(255), ID varchar(255), GROUP varchar(255), OAC_RT double, OUC_RT
double, OAT_RT double, OUT_RT double, OFN double, OFP double, OFP_RT double,
TAC_RT double, TUC_RT double, TAT_RT double, TUT_RT double, TAD_RT double,
TUD_RT double, TFN double, TFP double, TFP_RT double, OFP_PERC double,
OFN_PERC double, OTD_PERC double, TFP_PERC double, TFN_PERC double, TTD_PERC
double, SEX varchar(255), AGE double, EDUC double, EMP_STAT double, MAR_STAT
varchar(255), NART_IQ double, BDI double, SANX_ERP double, TRAIT double, GHQ
double, IES_A double, IES_I double, IES_TOT double, CAPS_BF double, CAPS_BI
double, CAPS_B double, CAPS_CF double, CAPS_CI double, CAPS_C double,
CAPS_DF double, CAPS_DI double, CAPS_D double, CAPS_F double, CAPS_I double,
CAPS_TOT double)
Error in sqlSave(channel, zz, addPK = TRUE, verbose = TRUE) :
[RODBC] ERROR: Could not SQLExecDirect37000 1064
[unixODBC][MySQL][ODBC 3.51 Driver][mysqld-4.0.24_Debian-10sarge1-log]You
have an error in your SQL syntax. Check the manual that corresponds to your
MySQL server version for the right syntax to use near 'GROUP varchar(255),
OAC_RT double, OUC_RT double, OAT_RT double
How can I avoid this error? Is there an option to sqlSave or should I
modify the names in the data frame?
TIA and take care, Darren

I would like to make one of the columns in a data frame the primary key. Using RODBC it seems that it always specifies a numerical index 'rownames' and you only have a choice of renaming that variable (rownames = "char") and setting it as the primary key (or not). I would like to not have this variable in the db table and just use another variable as the primary key (something like 'patient name' or 'id'). Is this possible?

I've discovered that the problem in this command is the use of 'GROUP' as a column name. Within mysql, we get the same error with: mysql> create table tmp ( group varchar(20) ); ERROR 1064: You have an error in your SQL syntax. Check the manual that corresponds to your MySQL server version for the right syntax to use near 'group varchar(20) )' at line 1 This page documents the reserved words in MySQL: http://dev.mysql.com/doc/refman/5.0/en/reserved-words.html It is possible to use the word 'group' as a column name, but it must be quoted with back-ticks (all other quotes fail), eg: mysql> create table tmp ( `group` varchar(20) ); Query OK, 0 rows affected (0.10 sec) mysql> desc tmp; +-------+-------------+------+-----+---------+-------+ | Field | Type | Null | Key | Default | Extra | +-------+-------------+------+-----+---------+-------+ | group | varchar(20) | YES | | NULL | | +-------+-------------+------+-----+---------+-------+ 1 row in set (0.00 sec) Sorry for my ignorance of this issue, the RODBC library is working fine, maybe it could be revised to handle these exceptions.
