The error is coming from numexpr not compiling the expression correctly. Also, you might try making selector a str, rather than bytes: selector = (column == 'str-2') rather than selector = (column == 'str-2').encode(encoding) Be Well Anthony On Tue, Jun 4, 2013 at 8:51 AM, Jeff Reback jreb...@yahoo.com wrote: anthony,where am I going wrong here? #!/usr/local/bin/python3 import tables import numpy as np import datetime, time encoding = 'UTF-8' test_file = 'test_select.h5' handle = tables.openFile(test_file, w) node = handle.createGroup(handle.root, 'test') table = handle.createTable(node, 'table', dict( index = tables.Int64Col(), column = tables.StringCol(25), values = tables.FloatCol(shape=(3)), )) # add data r = table.row for i in range(10): r['index'] = i r['column'] = (str-%d % (i % 5)).encode(encoding) r['values'] = np.arange(3) r.append() table.flush() handle.close() # read handle = tables.openFile(test_file,r) result = handle.root.test.table.read() print(table data\n) print(result) # where print(\nselector\n) selector = (column == 'str-2').encode(encoding) print(selector) result = handle.root.test.table.readWhere(selector) print(result) and the following out: [sheep-jreback-/code/arb/test] python3 pytables-3.py table data [(b'str-0', 0, [0.0, 1.0, 2.0]) (b'str-1', 1, [0.0, 1.0, 2.0]) (b'str-2', 2, [0.0, 1.0, 2.0]) (b'str-3', 3, [0.0, 1.0, 2.0]) (b'str-4', 4, [0.0, 1.0, 2.0]) (b'str-0', 5, [0.0, 1.0, 2.0]) (b'str-1', 6, [0.0, 1.0, 2.0]) (b'str-2', 7, [0.0, 1.0, 2.0]) (b'str-3', 8, [0.0, 1.0, 2.0]) (b'str-4', 9, [0.0, 1.0, 2.0])] selector b(column == 'str-2') Traceback (most recent call last): File pytables-3.py, line 37, in module result = handle.root.test.table.readWhere(selector) File /usr/local/lib/python3.3/site-packages/tables-3.0.0-py3.3-linux-x86_64.egg/tables/_past.py, line 35, in oldfunc return obj(*args, **kwargs) File /usr/local/lib/python3.3/site-packages/tables-3.0.0-py3.3-linux-x86_64.egg/tables/table.py, line 1522, in read_where self._where(condition, condvars, start, stop, step)] File /usr/local/lib/python3.3/site-packages/tables-3.0.0-py3.3-linux-x86_64.egg/tables/table.py, line 1484, in _where compiled = self._compile_condition(condition, condvars) File /usr/local/lib/python3.3/site-packages/tables-3.0.0-py3.3-linux-x86_64.egg/tables/table.py, line 1358, in _compile_condition compiled = compile_condition(condition, typemap, indexedcols) File /usr/local/lib/python3.3/site-packages/tables-3.0.0-py3.3-linux-x86_64.egg/tables/conditions.py, line 419, in compile_condition func = NumExpr(expr, signature) File /usr/local/lib/python3.3/site-packages/numexpr-2.1-py3.3-linux-x86_64.egg/numexpr/necompiler.py, line 559, in NumExpr precompile(ex, signature, context) File /usr/local/lib/python3.3/site-packages/numexpr-2.1-py3.3-linux-x86_64.egg/numexpr/necompiler.py, line 511, in precompile constants_order, constants = getConstants(ast) File /usr/local/lib/python3.3/site-packages/numexpr-2.1-py3.3-linux-x86_64.egg/numexpr/necompiler.py, line 294, in getConstants for a in constants_order] File /usr/local/lib/python3.3/site-packages/numexpr-2.1-py3.3-linux-x86_64.egg/numexpr/necompiler.py, line 294, in listcomp for a in constants_order] File /usr/local/lib/python3.3/site-packages/numexpr-2.1-py3.3
